RFID technology for time recording and access control

RFID (radio frequency identification) is a wireless identification technology that uses electromagnetic waves. First used by the military in logistics in the 1940s, it was later developed as a cost-effective method of contactless identification.

An identification medium, also known as a transponder, contains a microchip on which information (e.g. a serial number) is stored. Connected to the microchip is an antenna which facilitates wireless communication between the microchip and a reader. Identification media are available in various forms, such as cards or key fobs.

In the case of passive identification media, such as company ID cards used for time recording and access control, the microchip is also powered by the antenna. Active identification media, such as car keys with remote control, have their own battery to supply power to the microchip.

In addition to classic RFID technologies operating at 13.56 MHz, UHF RFID is also becoming increasingly important for access control, particularly where greater reading ranges are required for the identification of vehicles or individuals.

UHF technology enables reading ranges of several metres and is therefore ideal for access control in car parks, company premises, and warehouses, for example.

Outdated RFID technologies pose a risk to security and future viability.

Many companies are still using outdated RFID ID card technologies, unaware of the security risks involved. Legic Prime, MIFARE Classic and HITAG are still widely used, but they are no longer state of the art. These technologies offer insufficient encryption and are susceptible to copying and cloning attacks.

For future-proof systems, we therefore recommend modern, encrypted technologies.

• MIFARE DESFire EV3

In addition to providing significantly higher security, these RFID processes offer faster read/write speeds, increased storage capacity and a wider range of applications, including access control, payment processing, print management and locker control.

With a well-thought-out migration strategy, whether implemented step by step or with a cut-off date, existing systems can be upgraded to the latest technology.
