问题 I have written a program to communicate with a smart card (Gemalto Company MPCOS applet). I could successfully connect to card and transmit commands and fetch data. However I have a problem: When I used 00 A4 01 00 02 02 00 command to select DF(Dedicated File), It returned error 69 81 (file indicator is incorrect).

Sachin D I found an answer,the ACS now provides android library and sample application for their readers.You can find library here and some information and video demo of android supported readers is here . The only problem is that ACS android library supports only Android 3.1 and above. hope
