| + | == Cartes MiFare Ultralight == |
| + | MiFare Ultralight cards typically contain 512 bits (64 bytes) of memory, including 4 bytes (32-bits) of OTP (One Time Programmable) memory where the individual bits can be written but not erased. |

| + | |
| + | MiFare Ultralight cards have a 7-byte UID that uniquely identifies the card. |

| + | === Mémoire EEPROM === |
| + | MiFare Ultralight cards have 512 bits (64 bytes) of EEPROM memory, including 4 byte (32 bits) of OTP memory. Unlike Mifare Classic cards, there is no authentication on a per block level, although the blocks can be set to "read-only" mode using Lock Bytes (described below). |
| + | |
| + | EEPROM memory is organised into 16 pages of four bytes eachs, in the following order: |
| + | |
| + | <nowiki> Page Description |
| + | ---- ------------ |
| + | 0 Serial Number (4 bytes) |
| + | 1 Serial Number (4 bytes) |
| + | 2 Byte 0: Serial Number |
| + | Byte 1: Internal Memory |
| + | Byte 2..3: lock bytes |
| + | 3 One-time programmable memory (4 bytes) |
| + | 4..15 User memory (4 bytes)</nowiki> |
| + | |
| + | Here are the pages and blocks arranged in table format: |
