MIFARE® tags have revolutionised access control, transport and payment systems. These RFID (Radio Frequency IDentification) crendentials offer convenience, security and efficiency. In this article, we'll explore what a mifare tag is, why it works at 13.56 MHz, and how to program it for different applications.
What is a Mifare Tag ?
MIFARE is a brand of contactless smart card technology. These tags use RFID technology to communicate wirelessly with card readers. MIFARE badges are widely used for access control. They are available in several versions, the main ones being MIFARE Classic, MIFARE DESFire and DESFire EV2, each adapted to different applications.
Why 13.56 MHz?
The 13.56 MHz frequency is ideal for MIFARE technology, and here’s why:
Global compatibility: 13.56 MHz is a globally recognised frequency band that is not subject to licensing. This means that MIFARE badges can be used anywhere in the world without regulatory problems.
Reading range: The 13.56 MHz frequency offers an optimum balance between reading range and security. It enables secure short-range communication between the badge and the reader, reducing the risk of unauthorised access.
Interference Resistance: The 13.56 MHz frequency works well in a variety of environments and is less susceptible to interference from other electronic devices.
How do I program a Mifare RFID tag?
Programming a MIFARE RFID tag involves several steps:
Acquire the necessary hardware: You will need a MIFARE-compatible RFID enroller that operates at 13.56 MHz.
Read or Write Data: Use your software to read or write data to the MIFARE tag. You can customise access authorisations, add personal information or configure the badge for specific applications.
Security Considerations: Make sure you understand the security features of your tag. For secure applications, such as access control or payment systems, it is essential to follow best practices to prevent unauthorized copying or data theft.
CDVI’s Atrium range enables MIFARE tagss to be read directly, with no additional hardware required. Once the badge has been read, it can be retrieved, saved and assigned to a user. This procedure takes less than a minute.
In addition, for larger sites requiring the creation of a large number of badges, CDVI recently launched the new KPROG tag enroller. Its main functions are :
- IMPORT users from a CSV file
- CREATE a user
- READING a tag
- Aperio access management
- UPDATE an existing ATRIUM user
