2014-03-09 Thread sebastian nielsen
Hello. I have a Smart card, called CertGate, that was delivered with a properitary, precompiled JNI/NDK library. The smart card works by having the end user app access a file /cgmstrx.sdx in the root of the SD card. This works by having the end user app read/write APDU's to a interface in the
