What Is a Contact Smart Card?

A contact smart card is a card containing an integrated circuit that communicates with a compatible reader through physical electrical contacts. The card connects to the reader when its contact module meets the reader's electrical interface requirements.

Contact IC cards are used in systems that require direct electrical communication with an embedded chip. Depending on the selected IC and system design, the chip may provide memory storage, write-protection functions or password-based access controls.

Contact smart cards differ from contactless cards, which communicate wirelessly through a radio-frequency interface. A contact smart card and a contactless smart card are not automatically interchangeable.

For replacement projects, buyers should specify the existing card model, reader type, chip configuration and required data functions before selecting a replacement card.

Contact Smart Card Specifications

Kaisere Technology offers contact IC card configurations with material, printing and chip options for different B2B requirements.

Final card specifications follow the selected material, chip configuration and approved project requirements.

Which Contact IC Chip Fits Your System?

Choosing the correct contact IC chip is essential for system compatibility, data storage and card functionality. Kaisere Technology offers contact card configurations using the chip models listed below.

Contact Memory IC Options

These memory ICs have different memory organizations and security functions. The correct selection depends on the existing reader interface, card data structure, application requirements and system configuration.

AT24C Series Memory Options

The AT24C series uses an I²C-compatible two-wire serial EEPROM interface. Its memory capacity is expressed in kilobits, which should not be confused with kilobytes.

AT24C-series memory devices use a different electrical communication interface from the synchronous contact interfaces used by SLE/FM memory card ICs. Reader compatibility therefore depends on the selected card design and the existing system interface.

When ordering replacement cards, provide the original chip model, reader model or technical specification. Our team can use this information to define the appropriate card configuration.
