Hi, Does anyone know a tutorial on smart card which gives code example ? (The ISO 7816-4 standard is not easy to understand). My actual problem is to write more than 256 bytes in a memory card using only one time the write binary command. (I know it is possible to write up to 65536 bytes but i don't know how). Any help would be appreciated. (I have been involved with smart card for 12cdays only) Christian. *************************************************************** Linux Smart Card Developers - M.U.S.C.L.E.
