CARDS
COMMUNITY-BASED
The proximity card consists of a transponder (a chip connected to an antenna) laminated with PVC, which can be printed using offset or screen printing and finished with an overlay that protects the print and allows for sublimation personalisation. Card transponders are usually passive, which means they do not have their own power supply but rely on receiving energy from the proximity reader. Upon receiving this small amount of energy from the proximity reader, the tag transmits a response via the antenna. The standard reading distance is between 5 cm and 10 cm.
Types of chip
- Read-only:
The only information stored on the chip is the UID (unique identification number), which is unique.
Example: This number is used, for example, to link staff members to an access control system. This number can also be linked to a staff member in the access control/time and attendance software and assigned as their staff number. - Read/write:
The chip contains the UID but also has a memory in which information can be stored. The memory capacity ranges from 8 bytes to 8,192 bytes.
Example: each letter, number and punctuation mark is equivalent to 1 byte.

Ultra-High Frequency (UHF)
Our antenna design for UHF tags is ideal for medium- and long-range traceability applications, and is particularly well-suited to environments where radio frequency transmission is challenging. Its design ensures flawless performance over both short and long distances. We use the Impinj Monza 4 chip; the Monza 4 family offers a range of models for different applications, setting new standards in RFID privacy, improving the chip’s orientation tolerance, enhancing read/write performance, and increasing memory capacity.
