（ Note：_b That taking Anti-）
1、 No. 0,1 Page deposited with the card serial number and other information, is only readable.
2、Page No. 2,3 and A, B two data blocks, the data can be stored in general.
3、And 4,5-page for the numerical block may be used as a wallet, two-byte value to store positive and negative form.Only impaired operation, there is no value-added operations. If you do not do wallet to use, you can use as a common data block.
4、The first page stored in a password 6,7,8,9 A (6 bytes), the password B (6 bytes) and access control.
5、Page 7 of 2 bytes, page 9 of 2 bytes for the storage control, storage control to the form of being and existence against the two.

For example: AC-A of the initial value of ff, ie '11111111 ', namely:
Data1：Readable, writable;
Value： Writable；
AC-A：Writable；
Data2：Readable, writable；
6、Write a page (4 bytes) one time, read 2 pages (8 bytes)one time.
