Review on 🔒 YARONGTECH 13.56MHz 14443A Printable Classic Plastic RFID Card by Jeremy Black

I have several door locks that use classic Mifare credentials and other types of credentials. I currently have a variety of credentials so I know my locks are working great. These cards are NOT fully compatible with mifare classic 1k! Someone else asked if the cards were writable and the answer was no. This indicates that these cards cannot support the encrypted communications included in the Mifare specification. DO NOT ATTEMPT TO USE THEM FOR ACCESS CONTROL. If you use unencrypted credentials, you can just leave the padlock open all the time!
