Access Control in the Retail sector

A guide to Access Control in the Retail sector

What is access control?

Access control provides the ability to control, monitor and restrict the movement of people, assets or vehicles in, out and around a building or site.

Access control is essential in the protection of people and assets and has the additional benefit of being expanded from controlling, for example, a single entrance door to a large integrated security network.

There are also huge potentials in terms of integrating access control with other systems, such as CCTV and intruder alarms, allowing for cost savings and greater security benefits.

What risks does the retail sector face and how can these be countered by access control?

The retail sector faces a variety of threats all year round, including shoplifting, organised retail crime and dishonest staff, and these risks can increase significantly during busy shopping periods such as seasonal sales.

Recently, the BSIA carried out a survey of its members to discover the trends in retail security over the last year. Over 50% of respondents felt that the use of private security measures in retail had increased over the past twelve months, with a further 65% anticipating this use to increase over the course of the next year.

Members perceived the biggest threat to retailers to be shoplifting and petty theft, with theft by employees following in second. Online theft and armed robberies were also considered to be risks.

Retail environments are full of valuable assets, both on the shop floor and in the stock room. Access control systems are all designed to permit access only to people with the necessary authority to enter a particular area, ensuring that goods and people are protected and helping to manage known or anticipated threats.

Generally, systems are comprised of three main components:

1. The physical barrier – to physically restrict access to a building or area. This can be achieved through methods such as:

• Doors – secured by either a magnetic or strike lock, or can be revolving or sliding.

• Turnstiles and speed gates – designed to limit access to one person per identification device.

2. The identification device – there are a number of different technologies available to identify users of an access control system, including:

• A proximity card and reader via Radio-Frequency Identification (RFID) – these cards can be programmed to work at a short or long read range

• A smart card and reader

• A swipe card and reader

• PIN pads

• Biometric devices such as fingerprint or iris scanning

3. The door controller and software – these are at the heart of the access control system and are used to decide who can gain access through which entry point and at what time of the day are they permitted. These can vary depending on the size of the system and how many readers or sites you are trying to control from one point. Some of the options include:

• A stand-alone door controller linked to a single door with no software

• A number of door controllers all linked together to a single PC to control one site

• A number of sites all interlinked together over a wide network area

The added benefits of access control

Retail environments often incorporate large numbers of staff working varied shift patterns. Access control systems can offer a wide range of benefits, including Human Resource management and integrated security systems.

Time and attendance

Retail security does not necessarily just offer protection for the shop floor itself, but can encompass all stages of the supply chain – including staff offices, warehouses and even the delivery process. Naturally, various different employees and outside visitors are involved in these processes and access control systems can assist with staff management.

Badge/token technology can be used to record employee hours and monitor visitor movement within a specific site. If appropriate, these can be processed against working hours, applicable for both temporary and permanent staff – this can be useful for busy shopping periods when additional seasonal staff are employed temporarily. This can work in real time to feed transactions through to the company’s payroll. Time and attendance systems also accurately help keep employers on the right side of the European Working Time regulations and manage holidays and absences effectively. Fast, accurate and easy-to-use, these systems are suitable for businesses employing just a few people, right up to large multinational companies.

Automatic Number Plate Recognition

To monitor the movement of vehicles around an area, CCTV-style cameras and computer software can be used to identify number plates of vehicles. Some systems can also store photographs of the driver and vehicle for subsequent analysis.

This sophisticated software allows critical information to be passed to the police to assist in the pursuit, identification and capture of offenders should an incident occur. For example, if a shoplifter flees the scene of a crime via a vehicle, ANPR cameras situated around an area could help identify the criminal. Visual proof of parking offences with the corresponding time and date information is provided as evidence and to avoid disputes. Using a Driver and Vehicle Licensing Agency (DVLA) link, monitors are then able to identify the owner of a vehicle and process the offence automatically.

Fire roll call

Health and safety is a key consideration for any business. Since retail environments involve multiple staff members with varying shift patterns, it can be difficult to keep track of all employees during an emergency. Fire roll call technology generates a report containing crucial information in relation to who is within the building and potentially where they are. This software operates via the access control smart card or fob that an employee uses to gain access to or exit a building. In the event of an emergency, the fire roll-call software alerts occupants to the emergency whilst simultaneously activating the report at a safe pre-determined remote point.

Please note: In order for the fire roll call software to effectively carry out its function, employees and visitors must always present their card or badge. The use of smart card or RFID controlled turnstiles can help in this situation.

Integrated security systems

For maximum security, retail environments can benefit from a fully integrated access control system with CCTV, intruder alarms, fire detection and building management systems. One way to attain this is by adopting the use of Internet Protocol (IP) technology, which allows these systems to communicate with each other to maximise their effectiveness.

Separate access control and intruder alarm systems, for example, could allow an employee to access an area that is set with an alarm.

However, unless the employee has the authority to unset the system, the access would result in a false alarm being activated – potentially causing panic in a retail environment. An effectively integrated system would recognise that the user does not have the authority to unset the system, so would not allow them in the area to begin with.

What else should you know when considering access control?

An initial risk assessment of an area can determine the level of security required and subsequently influence the access control system you choose. BSIA access control members and professional security consultancies can assist with this.

BSIA members are subject to rigorous checks before they are admitted into membership, meaning that you are selecting a quality company. Below are just some of the reasons why BSIA members can offer you peace of mind:

• They are independently inspected to the quality standard ISO 9001 with a UKAS accredited inspectorate

• They comply with relevant British and European Standards and codes of practice

• Are financially sound

• Professional

• Staff vetting has been conducted where necessary

• They are technically proficient and committed to quality training and development

• They are up-to-date with the latest developments in British and European policy and legislation

What legislation should you be aware of?

The Disability Discrimination Act was amended in 2005 and has a significant impact not only in terms of the design of new systems, but also means that many systems may need to be upgraded to ensure compliance and adequate, user friendly access to the building for all staff and visitors.

Other considerations to be aware of:

National minimum care standards

Health and Safety at Work Act

Occupiers Liability Act
Management of Health and Safety at Work Regulations.

What happens during a fingerprints scan

What happens during a fingerprints scan?

What is a Fingerprint?

The skin surface of the fingers, palms and soles of the feet is different to the rest of the body surface. If you look at the inner surface of your hands and soles of the feet you will see a series of lines made up of elevations which we call 'ridges' and depressions which we call 'furrows'.

These ridges and furrows can be recorded in many ways. For example, the ridges can be inked and placed on to a piece of paper. This would leave a fingerprint like below. The black lines represent the ridges and the white lines represent the furrows.

Within these patterns the ridges can split or end creating ridge characteristics. There are 6 types of ridge characteristics.

Everyone has a unique and different distribution of these characteristics that develop in the womb and are persistent throughout life.

It is the coincidence sequence of these characteristics that allow me to make identifications. The coincidence sequence is whereby I will find the same characteristics, in the same order with the same relationship to each other in both the crime scene fingerprint and the fingerprint on the form I am using.

Fingerprints unique:

It's pretty obvious why we have fingerprints—the tiny friction ridges on the ends of our fingers and thumbs make it easier to grip things. By making our fingers rougher, these ridges increase the force of friction between our hands and the objects we hold, making it harder to drop things. You have fingerprints even before you're born. In fact, fingerprints are completely formed by the time you're seven months old in the womb. Unless you have accidents with your hands, your fingerprints remain the same throughout your life.

Enrollment and verification

Suppose you're in charge of security for a large bank and you want to put a fingerprint scanning system on the main entry turnstile where your employees come in each morning. How exactly would it work?

There are two separate stages involved in using a system like this. First you have to go through a process called enrollment, where the system learns about all the people it will have to recognize each day. During enrollment, each person's fingerprints are scanned, analyzed, and then stored in a coded form on a secure database. Typically it takes less than a half second to store a person's prints and the system works for over 99% of typical users (the failure rate is higher for manual workers than for office workers).

Once enrollment is complete, the system is ready to use—and this is the second stage, known as verification. Anyone who wants to gain access has to put their finger on a scanner. The scanner takes their fingerprint, checks it against all the prints in the database stored during enrollment, and decides whether the person is entitled to gain access or not. Sophisticated fingerprint systems can verify and match up to 40,000 prints per second!

How fingerprint scanners work

a computer has to scan the surface of your finger very quickly and then turn the scanned representation into a code it can check against its database. How does this happen?

There are two main ways of scanning fingers. An optical scanner works by shining a bright light over your fingerprint and taking what is effectively a digital photograph. If you've ever photocopied your hand, you'll know exactly how this works. Instead of producing a dirty black photocopy, the image feeds into a computer scanner. The scanner uses a light-sensitive microchip (either a CCD, charge-coupled device, or a CMOS image sensor) to produce a digital image. The computer analyzes the image automatically, selecting just the fingerprint, and then uses sophisticated pattern-matching software to turn it into a code.

Another type of scanner, known as a capacitive scanner, measures your finger electrically. When your finger rests on a surface, the ridges in your fingerprints touch the surface while the hollows between the ridges stand slightly clear of it. In other words, there are varying distances between each part of your finger and the surface below. A capacitive scanner builds up a picture of your fingerprint by measuring these distances. Scanners like this are a bit like the touchscreens on things like iPhones and iPads.

Unlike ordinary digital photos, scans have to capture exactly the right amount of detail—brightness and contrast—so that the individual ridges and other details in the fingerprint can be accurately matched to scans taken previously. Remember that fingerprints might be used as evidence in criminal trials, where a conviction could result in a long jail sentence or even the death penalty. That's why "quality control" is such an important part of the fingerprint scanning process.

Here's how the process works with a simple optical scanner:

1.    A row of LEDs scans bright light onto the glass (or plastic) surface on which your finger is pressing (sometimes called the platen).

2.    The quality of the image will vary according to how you're pressing, how clean or greasy your fingers are, how clean the scanning surface is, the light level in the room, and so on.

3.    Reflected light bounces back from your finger, through the glass, onto a CCD or CMOS image sensor.

4.    The longer this image-capture process takes, the brighter the image formed on the image sensor.

5.    If the image is too bright, areas of the fingerprint (including important details) may be washed out completely—like an indoor digital photo where the flash is too close or too bright. If it's too dark, the whole image will look black and details will be invisible for the opposite reason.

6.    An algorithm tests whether the image is too light or too dark; if so, an audible beep or LED indicator alerts the operator and we go back to step 1 to try again.

7.    If the image is roughly acceptable, another algorithm tests the level of detail, typically by counting the number of ridges and making sure there are alternate light and dark areas (as you'd expect to find in a decent fingerprint image). If the image fails this test, we go back to step 1 and try again.

8.    Providing the image passes these two tests, the scanner signals that the image is OK to the operator (again, either by beeping or with a different LED indicator). The image is stored as an acceptable scan in flash memory, ready to be transmitted (by USB cable, wireless, Bluetooth, or some similar method) to a "host" computer where it can be processed further. Typically, images captured this way are 512×512 pixels (the dimensions used by the FBI), and the standard image is 2.5cm (1 inch) square, 500 dots per inch, and 256 shades of gray.

9.    The host computer can either store the image on a database (temporarily or indefinitely) or automatically compare it against one or many other fingerprints to find a match.

The matching algorithm finds out whether there is a match by comparing two templates extracted by the characteristic point extraction algorithm, specifically by comparing the positions of each characteristic point and the structure.

You need an Access Control Systems

Do you need an Access Control Systems?

Access control security systems are designed to restrict physical entry to only users with authorization. Many organizations, governmental and private, have started adopting access control security systems for physical entry into their facilities. Whether it is a simple non intelligent access control system like a punching in a password, or advanced biometric systems that scan and permit entry very specifically, there are many advantages to employing these security systems.
It is important for businesses of every size to keep important data and remove threats. All businesses acknowledge this basic security concern by placing locks on the door and giving keys to employees that need to access these locks. If you answer yes to any of the following questions, you may need access control systems:

• • Is a lost or stolen key a security threat to your business?
  • Time Based Control for Security Systems
  • Do you need different access for different employees and clients?
  • Would it be really beneficial to restrict access based on time or day?
  • Do you need a record of people’s “comings and goings?
  • Could your employees/clients be more secure?
  • Reduced Requirement for Manpower
  • Biometric Systems

Benefits of access control systems

The benefits of access control systems are thus many:

• Audit trail – With access control systems, you will have a record of every opening and attempted opening of each door or specific area. The audit trail can be valuable in resolving employee issues.
• Time/day restrictions – Do you have certain employees that should only be there at certain times and days. An access control system make more sense to control their access than to give them a key that allows access at any time or day.
• Lost or stolen keys – When keys are lost or stolen, it is an expensive process for a business to completely rekey each door. Access control systems allow you to remove access by deactivating the I.D. badges or other security credentials.
• Remote access control – Many access control systems allow you to control of all of the business’ locks from one main system. With access control systems, you can easily and quickly lock down your businesses in an emergency as well as add and remove credentials.

Design 1:

Design 2: Single Door

Design 3: 4-Door single controller.

Design 4: New Concept, PoE Based

Design 5: SYRiS Product with SQL Database, Multi-location. One SY230NT Controller can controll 4nos of Door. Practically i do many projects with this.

How the Access Control System WorksØ  The typical access control system consists of a card/ pin reader, electromagnetic lock or door strike, power supply system and a push button.
Ø  The valid and authorized card user must present the card to the security system.
Ø  Upon verification by the reader, the locking system will be de-energized and the door can be pushed open.
Ø  To exit the premises, the person will have to press a door lock release switch and the system will release the lock.
Ø  A power back up is also installed while fitting in the access control system.
Ø  A break glass is also incorporated in case of emergency.
