Mind blown π€―
Some smartphones sold in mainland China (like certain OPPO models) can read MIFARE Classic cards, crack the keys in seconds, store them, and then fully emulate the card directly on the phone.
No extra hardware. Just the phone.
Access control, transit cards, hotel keys⦠game over.
Huge thanks to Ian for showing me this in person. Really eye-opening how far NFC capabilities have gone in some regions.
Who else has seen this in the wild?
