4442 IC card function description

1. Each byte of the write protection area (the first 32 bytes) can be separately written and protected. After write protection, the content can no longer be written.

Change (ie cure data).

2. All data is readable before the password is checked correctly. If necessary, the data can be properly encrypted.

3. After the verification password is correct, it can be written or modified.

4. three-byte user password, after the correct check can be changed, valid until the card is powered off.

5. password error counter, the initial value is 3, the password check error 1 time, it will be reduced by 1, if the counter value is 0, then the card is automatically

Locked up, number

It can only be read out, no further changes can be made and password verification can no longer be performed; if it is not zero, one password check is correct.

, can be restored to the initial value.

6. byte address 21 ~ 26 for the user code, our company can set a global unique code for large users, in order to use

The user is uniformly issued and used (all cards cannot be modified after leaving the factory).

7. byte address 0 ~ 5, 6 ~ 7 has been written by the factory before leaving the factory, can not be changed.

8. Note that the password area is additionally addressed, not within 0~256 bytes.

4442 IC card considerations

1.4442 IC card has three security mechanisms: user password, unique code, solidified write. If the password is not checked correctly, then

Data cannot be written, and the written data cannot be changed once it is write protected (cured). Use unique code as the system

The identification of the IC card prevents the counterfeit card of the same model from entering the system.

2. The SLE4442 card can read the data of the whole card without a password, so the design should pay attention to the content encryption to prevent damage.

Identify the data format.

3. The whole card is not partitioned. Once the password is verified, the data can be written or modified to any address, so the design time

Care should be taken to properly cure the data and encrypt the data content to prevent unintentional data corruption or illegal data changes.

4. After the password is checked correctly, it can be read. Therefore, the design time program should prevent the destroyer from using the illegal interrupt program.

Go directly to the password to steal passwords.
