T5557 card is a multi-functional non-contact radio frequency chip card produced by Atmel Corporation of the United States. It is a 125KHz low-frequency card and has a large application market in China. For example, many hotel access control cards use T5557 cards. The chip has a total of 330bit (bit) EPROM (distributed into 10 blocks, each block is 33bit). Block 0 of page 0 is a parameter configuration block reserved for setting the T5557 operation mode. Block 7 on page 0 can be used as a user data block, or as a password to protect all data (if the password function is enabled in the configuration block), to prevent illegal rewriting of data. Blocks 1 and 2 on page 1 store the manufacturer's information and unique factory ID, which can only be read and cannot be changed. T5567 and T5577 are upgraded versions of T5557.
By modifying the parameter configuration block of the T5557 card, the t5557 card can be simulated as an ID card and HID card, so it is widely used in the copying industry of access control cards.
