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.

  • i am work on this problem from last year but its not solve – Ruby Bhullar Jun 21 '16 at 10:19
  • @RubyBhullar: As explained, the reader (or its driver) implements the APDUs, so look into its manual - I have not yet seen an ACS-38 and definitely not programmed for it. The default PIN is typically 0000; look into the data sheet of your chip for a possibly different value, and into the reader manual for the format of PIN verification command. If the reading already works (since it can be measured), verify and write should be reached easily. – guidot Jun 21 '16 at 10:50

    @RubyBhullar: Stack Overflow is a forum for asking questions to solve the problems yourself. I already stated that I don't have seen the reader, so further comments won't help. – guidot Jun 23 '16 at 06:57
  • Thanks For reply and in future if you find the solution then tell me – Ruby Bhullar Jun 23 '16 at 07:02
