ISO 7816 FM4442 2K Contact IC Cards with Barcode
DAFTags FM4442 contact IC cards are programmable memory cards for contact-reader systems that need a simple stored-value, membership, identification, or access record. The card must be inserted into a contact reader and uses the ISO 7816-3 communication protocol.
The FM4442 chip provides 256 x 8 bits of EEPROM and is compatible with SLE4442-based systems. The card can be custom printed and supplied with barcode, numbering, magnetic stripe, or encoded data depending on the project.
The Customer Pain Points
- The card must be inserted, not tapped: FM4442 is a contact IC card. It will not work with an NFC phone or a contactless RFID reader.
- The listed 2K capacity can be misunderstood: The chip uses 256 x 8 bits of EEPROM, which is 2 Kbit or 256 bytes. The user data area is smaller after manufacturer, issuer, identification, and security data are allocated.
- Write protection is permanent once set: The lowest 32 addresses have irreversible byte write protection. Decide which data must remain writable before production.
- The PSC and memory setup need a plan: Access to the memory is protected by a 3-byte secret code. The default PSC and the required memory layout should be confirmed with the reader and software supplier.
- Printed barcode and chip data must match: If a barcode or serial number is printed on the card, the printed value and stored chip data should be checked together before shipment.
What Is an FM4442 Contact IC Card?
An FM4442 contact IC card is a smart card with an embedded EEPROM chip and a gold contact pad. The reader touches the contact pad to read or write data.
The FM4442 is compatible with SLE4442-based systems and uses ISO 7816-3 communication. It is intended for contact-card applications, not contactless payment or NFC.
Key Features
- FM4442 Chip: Programmable memory card compatible with SLE4442 systems.
- 256 x 8 Bit EEPROM: 2 Kbit of memory with a structured data layout.
- ISO 7816-3 Protocol: Contact communication for compatible card readers.
- 3-Byte Secret Code: Data writing is protected by a PSC; reading is generally open except for the PIN area.
- Write Protection: The lowest 32 addresses have irreversible byte write protection.
- Custom Card Production: Barcode, printing, numbering, magnetic stripe, and encoding can be discussed.

Reader Compatibility
The card must be used with a contact reader that supports FM4442 or SLE4442 cards and the ISO 7816-3 protocol. It cannot be read by an NFC phone.
Send the reader model, software requirements, memory layout, and PSC setup before ordering. Test a programmed sample in the finished system before bulk production.

FAQ
Will this card work with our contact IC reader?
Only if the reader supports FM4442 or SLE4442 cards and the ISO 7816-3 protocol. Send the reader model before ordering so compatibility can be checked.
Is the card 2K in bytes or bits?
The chip has 256 x 8 bits of EEPROM, which is 2 Kbit or 256 bytes. The available user data area is smaller after other data fields and security bytes are allocated.
Can the card be read by an NFC phone?
No. This is a contact card and must be inserted into a compatible contact reader.
Can the write protection be changed later?
The lowest 32 addresses have irreversible byte write protection. Once the protection bit is programmed, it cannot be returned to a writable state.
Can the barcode match the chip data?
Yes. Provide the required barcode or number format and chip data layout so the printed value and stored data can be matched.
Can I request samples?
Sample availability depends on the current production schedule. Test the card with the actual reader and software before approving bulk production.
