Hi There,

We are working on Contactless card reader application for Nokia 6131.We are working with the 4 byte MifareClassic cards.But now have a requirement to support 7 byte UID on the same cards.

Till now we were using MFStandardConnection Interface to get the 4 Byte UID of MifareClassic card.

Now we need to get 7 Byte UID of MifareClassic 7 Byte UID cards.

GetUID method on MFStandardConnection Interface returns only 4 byte UID so unable to use it now.

I read somewhere that symbian SDK 3 includes the required JSR-257 extension. does anyone have any idea about the interface and method which could return serial number of card in this SDK for 7-byte?

Appreciate your input.
