MI-FARE Classic 1K RFID Smart Card with Hole (Vertical, 100)

In this review the MI-FARE Classic 1K RFID Smart Card with a hole is evaluated for small businesses and integrators who need reliable, writable 13.56MHz access and ID cards in bulk. The bottom line: these cards are straightforward, ISO14443A-compatible credential cards with a fixed 4-byte UID and 1K bytes of read/write memory, making them a practical choice when compatibility with common RFID readers and card printers matters more than advanced security features.

Key Features

• FUDAN FM11RF08 Chip: Provides a MI-FARE Classic 1K compliant chip with 1K bytes of read/write memory for storing access data and simple applications.
• ISO14443A Compatibility: Works at 13.56MHz with a wide range of readers and door locks that support the MI-FARE Classic standard, simplifying integration.
• Printable on ISO Desktop Printers: Blank white on both sides and CR80 size allows printing on most desktop photo ID card printers such as Evolis, Zebra, Fargo and Magicard.
• Pre-programmed Unique UID: Each card ships with an unchangeable 4-byte UID and factory default key FF FF FF FF FF FF for predictable provisioning.
• Hole for Lanyard: Cards come with a hole (vertical) for badge clips or lanyards, useful for events and ID wearability.
• Contactless Read Range: The laminated chip design supports contactless operation with a typical reading distance of 1-10 cm depending on the reader.

Who It's For

The MI-FARE Classic 1K cards suit system integrators, hotels, small businesses, and schools that need low-cost, writable RFID credentials for access control, time and attendance, or event badges. They are a good fit when using common readers like RC522 and PN532 or locks from KABA, SAFLOK, MIWA and ONITY.

These cards are not for projects that require high security encryption or compatibility with HID, Salto or Assa Abloy systems. Also avoid them if you need changeable UIDs or plan to print on inkjet printers, since they are intended for thermal/photo ID printers and arrive blank both sides.

Pros & Cons

Pros

• Clear compatibility with MI-FARE Classic readers and many access control locks makes integration predictable.
• Ready for printing on most ISO desktop photo ID printers, simplifying badge production.
• Pre-programmed unique UID and factory default key speed up provisioning and inventory tracking.
• Vertical hole provides convenience for wearable badge applications.

Cons

• Security is limited to MI-FARE Classic capabilities; this is not suitable for higher-security encrypted deployments.
• Cannot be used with HID, Salto or Assa Abloy systems and will not print correctly on inkjet printers.

Specifications
