This tool is for educational purposes and authorized security testing only. cards are considered insecure. Use on your own cards to understand NFC technology. 1. Prerequisites An NFC-enabled Android phone .
: Decodes complex access bits into an intuitive visual table to reveal which blocks are read-only or read/write.
The MIFARE Classic uses a proprietary stream cipher called Crypto-1. For years, it was considered secure. However, in 2008, researchers reverse-engineered the algorithm. By 2019 (when the core logic of MCT 2.3.1 was maturing), tools could break a 48-bit key in under 2 minutes using a standard smartphone.
