{{bloc-etroit|text=MIFARE Classic cards come in 1K and 4K varieties. While several varieties of chips exist, the two main chipsets used are described in the following publicly accessible documents:

{{bloc-etroit|text=Les cartes MIFARE Classic sont disponibles sous les formats 1K et 4K. Bien qu'il existe une variété plus importante de puce MiFare, ce tutoriel va se pencher sur deux chipsets principaux disposant de documents publiquement accessibles:

Mifare Classic cards typically have a '''4-byte NUID''' that uniquely (within the numeric limits of the value) identifies the card. It's possible to have a 7 byte IDs as well, but the 4 byte models are far more common for Mifare Classic. }}

Les cartes Mifare Classic ont typiquement '''4-octets NUID''' qui identifie de manière unique chaque carte (dans la limites des valeurs numériques codables sur 4 octets). Il est également possible d'avoir des modèles avec une identification sur 7 octets mais les modèles 4 octets sont, de loin, les carte Mifare Classic les plus répandues. }}

{{bloc-etroit|text=Mifare Classic cards have either 1K or 4K of EEPROM memory. Each memory block can be configured with different access conditions, with two seperate authentication keys present in each block.

Sector 0 is special since it contains the bloc Fabricant ("''Manufacturer Block''" en anglais). This block contains the manufacturer data, and is read-only. It should be avoided unless you know what you are doing.
