Solution

  • The SLE4442 is a memory card, no smart card. It does not understand any APDU, the translation to the communication protocol is done by the reader, see (among many similar ones) this question. Trying some different readers to find a faster one is surely an option. But I would definitely recommend to use a real smart card, where 115 kBit/s are easily reached.
