Product Description

This card works the same as the normal IC cards, for Mif 1K S50 standard. Only the Sector 0 Block Zero which is known as the Serial Number/Manufacturers Block(Chip UID) could be programmed to any UID you want.  


The product is as follows:

1,UID card block 0 (UID's block) can be modified arbitrarily.

2, block 0 directly with normal mifare read-write device modification.

3, card of the default password for 12 F,FFFFFFFFFFFF.


It can not revised UID by phone

Note: common 13.56 mhz rfid reader writer and nfc phone can not write the particular cards!
