10PCS 13.56MHz IC Writable Card GEN2 UID Changeable 1K Card block 0 MCT

Description

The first GEN UID chip and the GEN2 UID chip use different commands, so they need to use different software to operate. The second generation uid is also known as cuid.
1,The first generation uid used the back door command. The command of uid sector is different from that of other sectors.
2,The normal commands used by the second generation UID cuid are the same as those used by other sectors
This means that if your software is used in the first generation card reader, it can not be used in the second generation card reader. The second generation reader can use Android NFC to rewrite uid compared to the first generation reader
If you don't have the software to write the second generation uid, even if you have professional equipment, I don't recommend buying this product. Of course, if you have an Android phone with NFC, you can modify the uid with MCT software
Item Compatible with S50, Support Android APP MCT(Do not provide, download it via play store by yourself.
)
