Review on YARONGTECH-13 Commercial Door Products by Abdullah Huan

I have several door locks that use Mifare Classic and other types of ID. 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!
