Flexible migration and
scalable security

The route from prime to advant

The CTC platform creates individual and flexible migration scenarios for today’s users of prime applications. Instead of having to replace the entire installation in one step, with the CTC platform the smartcard IC can be switched over to advant and the readers of individual areas to 4000 or 6000 series step by step. Once the full migration to advant has been completed, if desired the LEGIC RF standard interface can be indefinitely disconnected.

Easy migration

from prime to advant with the CTC


LEGICs CTC (Cross-Standard Transponder Chip) is the solution for a flexible migration to LEGIC advant. The CTC platform enables users to move between installations with different RF standards. This means that, depending on security requirements, individual areas can be selectively designed and implemented with prime, 4000 or 6000 series reader ICs.

Investment security
& sustainability

The CTC comes with pre-configured, confidential key material as a standard and uses modern encryption algorithms. At the same time, there is a prime memory on the chip: a LEGIC reader IC can also access the prime memory via the advant interface.

card design

The CTC is a single smartcard IC for different RF standards on one identification medium.  For ID media manufacturers, this means a simplified card design with only one antenna and lower costs.
