RFID: understanding technologies to choose the right cards

RFID is now at the core of identification and access control systems. Widely used across professional environments, it ensures smooth and secure access management. However, choosing the right technology requires a clear understanding of how RFID works.

Main RFID frequencies

Two main frequency ranges dominate the market. Low frequency (125 kHz) is commonly used in older or simple systems. It is easy to deploy but offers limited security.

High frequency (13.56 MHz), on the other hand, includes advanced technologies such as MIFARE and DESFire. These solutions provide enhanced data security and are widely used in modern systems.

Differences between MIFARE and DESFire

MIFARE Classic has long been a standard, but it is now considered less secure. It is still widely used in existing installations.

DESFire cards offer a higher level of security thanks to advanced encryption mechanisms. They also support multi-application usage, making them ideal for complex environments.

How to choose the right RFID card

Choosing the right RFID card depends on your system. It is essential to verify frequency, technology, and encoding requirements.

Selecting the wrong product may result in incompatibility. This is why relying on technical expertise is key to ensuring proper integration.
