Overview

A white contact IC card for readers and development projects that explicitly support SLE4442. Electrical contact with a compatible reader is required; this is not an NFC card.

Features

• SLE4442 model with 256 bytes of main memory (2048 bits / 2 Kbit).
• Synchronous two-wire communication. Check explicit SLE4442 support, rather than relying on an ISO7816 label alone.
• White card surface and metallic contacts; supplier dimensions are 85.5 × 54 mm.

Specifications

Use and Care

1. Check that both reader and software explicitly support SLE4442.
2. Insert the card as directed by the reader and read its information. Back up data before writing.
3. Obtain the correct security code for the card before writing; do not assume a default code or repeatedly guess it.

Write protection can be irreversible. The chip datasheet describes security-code and error-counter mechanisms; card initialization depends on the supplied batch. NFC phones and the PN532 NFC HAT cannot directly read or write this contact card.

Stacked cards illustrate appearance and do not specify a bulk pack. Pack quantity must follow the final sales option. A reader is not part of the pictured product.
