You should not use the Write EEPROM command from your application. Starting with Series 3 BasicCards the parameters to this command are encrypted, so only ZeitControl knows how send valid Write EEPROM command sequences to the cards. If you're unlucky, you can ruin your card by trying to write to the EEPROM this way.

If you want to save data (like your ID) on the card, you'll have to write a program for that card which then provides a defined interface to read and write data. See the Examples folder and have a look at the "Debit" example to get an idea how this works.

Another possibility would be to create a filesystem on the card and use files to store data. See the BasicCard manual and the "FileIO" examples for more information.
