API provides access to MIFARE specific I/O operations on a Tag.

Required Header

#include <nfc.h>

Overview

MIFARE Classic is also known as MIFARE Standard.
MIFARE Classic tags are divided into sectors, and each sector is sub-divided into blocks. Block size is always 16 bytes.

MIFARE Classic Mini are 320 bytes (SIZE_MINI), with 5 sectors each of 4 blocks.
MIFARE Classic 1k are 1024 bytes (SIZE_1K), with 16 sectors each of 4 blocks.
MIFARE Classic 2k are 2048 bytes (SIZE_2K), with 32 sectors each of 4 blocks.
MIFARE Classic 4k are 4096 bytes (SIZE_4K). The first 32 sectors contain 4 blocks and the last 8 sectors contain 16 blocks.

MIFARE Classic tags require authentication on a per-sector basis before any other I/O operations on that sector can be performed.
There are two keys per sector, and ACL bits determine what I/O operations are allowed on that sector after authenticating with a key
