Chipcards


Provided with Chip, the to-days plastic card has moved more and more into the direction of being an electronic key. There is hardly any limitation for the use of these cards. The chips inside can be used for a wide variety of applications such as: cash free payment, computer access or registration of loyalty points in a customer loyalty program.

An advantage of the chipcard in comparison with cards using a barcode or magnetic stripe, is that the chip allows secure data storage. The use of a pincode and data encryption are very useful means to secure the data against misuse. Chips are divided into 2 versions: A) Low-Cost memory chips. These again are divided into versions with

1) I2C-Bus memory without security logic.

2) Secure memories with security logic and

3) Secure memories with security logic and data encryption.

When highest security is demanded, the more sophisticated Micro Controller Chips are used. This chip is to be seen as a little computer with lots of security features, allowing highly complex data encryption. Micro Controller chips are divided into

Chips with ROM (read only memory)

RAM (random acces memory)

EEPROM (Eletrically Erasable Programmable ROM)

Card Service manufactures the cards with the required chips and encodes these according to customer requirements.

Furthermore Card Service supplies a variety of components for the reading and writing of chipcards. The most common actual chip types are shown below.
