The RFID contactless key fob is one of the most important RFID identification media for contactless data transmission. The key fobs are available in different coloured cases and can be equipped with different technologies (e.g. LEGIC, Hitag, EM, Mifare). In addition, we personalise the key fobs, as requested, with one RFID chip or two chips inside, and printed with the company logo, photo, number etc.
The highlight: different technologies can be combined in a RFID keyfob ! Other forms and materials are available. You can choose material of ABS,PC,PPS,PVC .There is a large number of applications for these RFID designs. Ranging from time recording and access control to the control of lifts, barriers, vending machines, alarm systems, petrol pumps, car washes and petrol stations etc. You can use one combination RFID contactless for multually aplication.
EM4200 is a CMOS integrated circuit intended for use in electronic Read Only RF transponders. It is designed to replace directly the EM Microelectronic-Marin Read Only ICs EM4100/4102 and EM4005/4105.
Compared to EM4100/4102 and EM4005/4105, the chip provides higher reading range performances and presents on its coil terminals bigger resonant capacitor (210pF and 250pF selectable by mask option).
The 128 bit unique code is stored in laser programmed ROM. Several options are available to use 64, 96 or 128 bits of ROM.
The circuit is powered by an external coil placed in an electromagnetic field and gets its master clock from the same field. By turning on and off the modulation current, the chip will send back the unique code contained in a factory pre-programmed laser ROM.
The feature of Legic ATC4096 is :
Contactless Interfaces: 13.56 MHz, ISO14443 A or ISO15693 compliant
Memory: memory sizes from 128 bytes up to 4096 bytes. Segments and read/write privileges can be dynamically defined from 16 up to 4096 bytes per application
Multi-Application: easy plug & play multi-application for up to 127 applications
- System security & control and key management based on physical tokens (LEGIC Master-Token System Control). Physical token based security avoids
insecure passwords and directly translates into true system control for the system owner.
- Encrypted data transfer and encrypted data storage can be defined per
application (AES 128/256 bit, 3DES, DES, LEGIC encryption).
- All LEGIC transponder chips contain a unique transponder ID (UID) and
come with LEGIC SafeID feature (authenticated UID) for enhanced trust.
- EAL4+ CC certified hardware (ATC4096)
Cross-type API: a common API for all LEGIC advant transponder types is
provided for easy and time efficient design-in
