Access control is one of the most important aspects of physical security in a commercial setting. Unauthorised visitors and personnel can gain access to confidential assets if these systems are not properly managed, which can have detrimental effects on a business. A popular access control system used by many business owners across the UK are proximity card systems.
In this blog post, we will discuss proximity card systems, the various types, and the benefits of installing them on your commercial property.
What is a Proximity Card System?
A proximity card system consists of two components: a proximity card and a proximity card reader.
A proximity card is a low frequency, 125kHz contactless card with an embedded metallic antenna coil that allows users to enter a building when detected by a proximity reader. The card stores data, which is picked up by the reader to either allow or deny access to a building. The readers are linked to an internal lock control system that regulates access to a building or a specific area within it.
These systems use advanced technology known as Radio Frequency Identification (RFID). RFID technology enables proximity card readers to communicate with access control systems via radio waves with a single tap or wave.
Types of Proximity Card Readers
- Wired Proximity Readers
These are the most popular proximity readers in commercial facilities across a variety of industries. They have been around for decades and are used with nearly every access control system. They use a range of protocols, including the very popular Wiegand protocol, to communicate with proximity cards.
- Wireless Proximity Readers
These readers are battery-powered, eliminating the need for complicated wiring. They are frequently used as part of hotel security systems and apartment complexes where it would be costly or difficult to wire readers into each door. They are usually linked to a wireless repeater that communicates with the central control panel.
- IP-connected Proximity Readers
These card readers are the most advanced and secure of all proximity readers because they can connect and work via Ethernet, with many being powered over the network connection via PoE (Power over Ethernet). This means that the systems are not directly connected to an access controller, meaning they cannot be intercepted by unauthorised parties attempting to gain access to your facility. These systems are best suited for industries where privacy and data security are critical, such as government agencies and financial institutions.
Benefits of Proximity Card Systems
1. Enhanced Security
A major advantage of proximity card systems is their ability to significantly improve a facility’s security measures. When compared to traditional lock-and-key systems, proximity card readers are extremely difficult to bypass, adding an extra layer of security to businesses.
Unlike locks and keys, they are difficult to duplicate, making it more difficult for unauthorised visitors to enter your building. Furthermore, most access control technologies use encryption to ensure the security of transmitted data, significantly reducing the likelihood of cloning or hacking.
2. Improved Hygiene
Other access control systems, such as keypads which require users to touch the access reader for authentication are unhygienic. This is especially true for commercial facilities in industries like healthcare and education, where germs spread easily, and people are more vulnerable to bacteria and diseases.
3. Cost-effective
Proximity systems tend to be very affordable. The low cost of access control technologies such as cards or fobs, combined with the long-lasting durability of the readers themselves, makes them a cost-effective solution for businesses. Furthermore, their ease of installation and low maintenance requirements help to reduce overall costs.
4. Auditable activity
Another significant benefit of these systems is that they generate data that can help businesses better monitor access to their facilities. These systems enable businesses to create detailed audit trails and reports.
Each time the card is used, the system records the event, including a timestamp, the unique proximity card reference number, and the specific door or area accessed, providing valuable information for security personnel in the event of an incident. This will help with investigations, improve loss prevention methods, ensure accountability, and identify potential security vulnerabilities.
5. Safety Reporting
Although often used to control access, these systems can be invaluable for reporting on-site personnel during an emergency. When proximity cards are used for access and egress from a building, a report can be generated for emergency roll call.
