Hello SmartCard Linux hackers ! Hi! I have recently bought a package from TOWITOKO CHIPDRIVE linuxpack which includes 2 memory cards. Those two cards seems to be of a different type: - 2Kbit I2C EEPROM Card (256 Byte, R/W) seems to be a 2-wire card (icc-type = 2) - 16Kbit I2C EEPROM Card (2048 Byte, R/W) seems to be a IC2 SHORT card (icc-type = 0) I don't know why these cards of different sizes are also of different types... ? Why not? But now to the problems: The ATR of the 16Kb card is always empty (NULL pointer, as it is no 2-/3-wire card). Is this implementation in the CT code correct ? A memory card does return no ATR... In fact, the reader might return one, if it wants to... And now the main problem: - The 2Kbit card seem to need the PIN code, is this correct (I cannot write on it, and I saw in the code, Yes, memory cards can have PIN codes entered. The method used to enter this PIN is 'implementation defined', i.e. you should ask your card manufacturer. that on type==2 and 3 cards, the PIN entering is always done. I have not seen any PIN (in the package, on the card, etc) So I don't know any key, and now the card always blocks PIN entering, as the retry counter is already on '0'. Can I do here anything ? If this is a real PIN code, and the card can't be reset, too bad... Good luck! -- Erwann ABALEA [EMAIL PROTECTED] RSA PGP Key ID: 0x2D0EABD5 - No wanna work.

Hi, which includes 2 memory cards. Those two cards seems to be of a different type: - 2Kbit I2C EEPROM Card (256 Byte, R/W) seems to be a 2-wire card (icc-type = 2) If it's I2C, then it isn't 2-wire. If the Towitoko driver assigns '2' to the ICC type then it migth be an 2-wire card. - 16Kbit I2C EEPROM Card (2048 Byte, R/W) seems to be a IC2 SHORT card (icc-type = 0) I don't know why these cards of different sizes are also of different types... ? Because of the protocol used to communicate with the card is diferent. But now to the problems: The ATR of the 16Kb card is always empty (NULL pointer, as it is no 2-/3-wire card). Is this implementation in the CT code correct ? Yes. I2C cards does not return ATR. So The driver leaves this data blank. The CT spec does not says nothing about this being incorrect, so I guess it's fine. And now the main problem: - The 2Kbit card seem to need the PIN code, is this correct Yes, you need to enter a PIN. The cards that come with the beginers pack use to have PIN=000. (I cannot write on it, and I saw in the code, that on type==2 and 3 cards, the PIN entering is always done. I have not seen any PIN (in the package, on the card, etc) So I don't know any key, and now the card always blocks PIN entering, as the retry counter is already on '0'. This is because somebody (I don't mean you ;-) entered a wrong PIN 3 times, or because the card is bad. Can I do here anything ? I also want to contact TOWITOKO (german company), the cards and card reader are coming from. If the card is actually blocked, you cannot. Please help. I will further study the code to understand the PIN protocol and PIN handling. I have not found the spec for the security (PIN) handling and protocol yet. I don't know of such specification. You just need to use the appropiate CT commands (see MKT specs) to send PIN, change PIN, etc. __ Do You Yahoo!?
