In terms of access control, a door access reader is the first security measure people encounter when trying to enter a space. In order to gain entry with a proximity card reader, the user needs to have an authorized proximity card on their person. Proximity cards and readers use RFID (radio frequency identification) to communicate wirelessly, with authorization data encoded on the cards.
Proximity readers work well for commercial building security. They can be programmed to meet various needs. Before installing an access control system with proximity card readers, understand the different reader types. Also, consider the benefits and drawbacks of a proximity card reader system.
Types of proximity readers
While many proximity readers may look the same, they can function very differently depending on their power supply and how they connect back to the access control system. There are four common types of proximity card readers available for access control. When installing proximity card readers, it’s important to know which type provides the best security for your space.
Wired proximity readers: Catering to the physical security needs of buildings since the 1970s, wired proximity readers use the Wiegand protocol to communicate with other devices.
Wireless proximity readers: Wireless proximity readers run on batteries, so you don’t need to wire them back to a control panel. They work best in large deployments, such as hotels and apartment complexes, where wiring each individual door would be too costly. They usually require localized access points throughout the building to communicate with an Internet-connected central control panel. One of the downsides of this type of proximity reader is the need to check and replace batteries to ensure proper functionality.
Standalone proximity readers: These decentralized card readers don’t connect to the access control panel. They are ideal for single-door small offices that don’t need advanced security features.
IP-connected proximity readers: This more advanced type of reader has no direct connection between the reader and controller. The Ethernet connection allows them to be fully integrated into IT systems for a more automated, flexible security system. However, it’s important to note that this type of system should meet high-level encryption and cybersecurity standards to ensure your space is secure. If your IP is compromised, your building security is also at risk.
Benefits of proximity card readers for access control
Harder to Clone
One major factor that shifted security away from traditional lock and key systems is the ease of cloning and manufacturing key copies. Many industries have moved on from this outdated method. Hotels are one of the most common examples.
Proximity Card Readers are used worldwide. You can find them in hotels, retail, gyms, transportation, rentals, and more. Proximity technology is hard to copy. It is not as easy to access as visiting a local locksmith.
Easy Integration
Proximity Card Readers are simple to install and integrate with your current systems and plays well with others. It is very commonly used alongside different types of security, from CCTV to two-factor identification, to biometrics.
This is one of the main reasons that Proximity Cards are used in a variety of industries (more on that later), and are very popular with small and large businesses alike.
Contactless
The fact that Proximity Cards are contactless has a whole plethora of benefits, especially since the prevalence of, and need for contact-free services and access.
Whether you are looking to improve your operations, reduce physical contact, or move away from traditional security methods, this provides a viable solution.
Proximity Cards are often confused with Key Fobs as they use very similar methods and technology, but there are a few differences between Proximity Cards and Key Fobs to be aware of.
Lower Chance of Wear & Tear
Due to the nature of the system, there is very little operational, to no, wear & tear damage done when the cards are read and the proximity reader is used.
This is because there is no physical contact between the two parts of the system, the credential (card) is not inserted into the reader, nor does it have any real moving parts.
This means that the typical everyday damage that a lock and key might encounter is negated and avoided.
Security concerns of proximity card readers
Insufficient read range
The read range is the distance from which the reader can detect a nearby credential. The read range will vary by device. Distance is an important consideration when installing a security system. For example, a turnstile gate or front door should have a shorter read range so that people need to be close to the reader to request an unlock. This will help prevent tailgating incidents. However for parking garage deployments, the read range needs to be farther to account for vehicle size and the ability for users’ credentials to communicate with the reader from inside the vehicle.
Hackable backend hardware
Door access readers are unfortunately a popular target for criminals who want to steal data and vandalize businesses. One thing to keep in mind when installing new readers is backwards compatibility. If you use outdated legacy backend hardware for your security system, advanced prox card readers may face security risks. In a hybrid access control model, choose a system with end-to-end encryption at every communication level. Add extra protections against hardware hacking.
Data stored locally
some proximity readers store data at the local level, making it easy for potential criminals to gain access to it. This often-overlooked security pitfall could compromise your entire system. Openpath’s card readers are set up as a blind proxy between the credential and control unit, so they offer no value to hackers looking for a way in. They also have built-in alerts against tampering.
No backups or fail safes
In the event of a power or Internet outage, having a backup power source ensures your system stays operational. Without a backup option or failsafe protocol, you risk locking people out or leaving doors unlocked. Make sure your system supports offline functionality to prevent getting locked out during an emergency. It should also offer a way to connect to an alternative power source or backup battery.
What industries can benefit from Proximity Card Readers?
- Corporate
- Health and Medical
- Private and Residential
- Car Parks
- Retail and Consumer Goods
- Airports and Transportation
- Logistics
Is a proximity card reader system right for your space?
Before deciding on a system, ask yourself what is most important for your building security. To combine mobile access control credentials with prox cards, ensure that the proximity readers you choose support flexible credential types. Openpath provides encrypted DESFire EV2 access cards, which work seamlessly with mobile credentials. Additionally, Openpath is compatible with many legacy access cards, so you won’t need to re-issue new prox cards to your entire organization after installing Openpath Smart Readers or an intercom reader system. Security experts also recommend cloud-based access control solutions, as they offer enhanced security and easier remote management. Openpath’s cloud-based software ensures a smooth transition, with seamless integration with leading directory management platforms to sync users automatically. Plus, the remote platform allows admins to instantly issue or revoke credentials at any time.
If you’re thinking about installing a proximity card reader access control system for your space, schedule a site walk with a security expert. They’ll perform a security audit, evaluate your space, and identify where and what type of system is best for you.
