CARDS
WITH A CONTACT CHIP
We offer our customers cards featuring the most widely used contact chips available today, from the most reputable manufacturers. These chips provide greater security for the information stored on your cards and may feature freely accessible memory (read/write access without a PIN). We stock EPROMs with capacities ranging from 1 Kbit to 1 Mbit.
Serial memory
Protected memory (PIN-protected read/write access). These devices use a synchronous protocol and are available with 1 kilobit, 1.5 kilobits or 16 kilobits of EEPROM memory for use in smart card applications.

Crypto memory
Crypto memory is a wide range of memory devices which, despite their low cost, offer a high level of security whilst operating on both synchronous and asynchronous protocols. These devices operate using the same T=0 protocol but do not require an operating system, making them easier to programme.
