Comparing RFID and NFC access control
When putting in an access control system, today’s market will present you with plenty of options. From which type of ID badge to choose, to where to put access points, to how you want to authenticate cardholders, there are certainly a lot of choices to be made. But when it comes time to choose between RFID and NFC card readers, it can be difficult to tell the difference between the two technologies. It isn’t exactly comparing apples to oranges each type of reader has its own benefits and drawbacks.
RFID Technology in physical security
RFID stands for Radio Frequency Identification. RFID technology makes use of electromagnetic waves to capture and read transmitted data. Information is electronically stored on a tag attached to an object or to the carrier, and that tags chip is activated when it’s near the reader enabling it to share the access information it holds.
RFID IN DOOR ACCESS CONTROL SYSTEMS
The most common use of RFID in access control is in door entry systems for personnel. In this case, RFID-enabled tags are usually employed on a very basic level as the identification badges for workers, providing a simple solution for any company or industry that uses access control systems. Door readers use this same technology: Each RFID reader is equipped with a small antenna.
RFID SOFTWARE
The access control software system reads the data taken from signals received from each RFID reader, enabling readers to accept and deny requests to access certain amenities based on access levels or specific permissions Access panels, which are parent devices that control card readers and make these grant and deny decisions, allow for easy integration with RFID readers. Access control panel hardware is needed to open the lock door, which is only done when the proper access is granted to each authorized cardholder
RFID-based technology is widely used in today’s market, and you’ve probably at least heard of this sort of technology before reading this article There are many companies that manufacture RFID tags and readers, and you will have a great deal of freedom in choosing the technology that is right for your space
Benefits of RFID
RFID chips are able to handle much more of a beating compared to barcode technology, which keeps your employees from worrying about accidentally damaging their cards. There is virtually no fear of wear and tear; in most circumstances and RFID card would still be able to send its embedded information.
DRAWBACKS OF RFID
There are distinct issues with uncertainty and unreliability when dealing with RFID cards and technology because any technology that can create a signal has the potential to be hacked. For starters, there is a possibility that any person equipped with an RFID reader could access the information embedded on each card, which cannot discern between a friendly reader and a hostile one.
