IMVHO To be contactless is kind a feature, so a "request card features
function" (like frequency, memory, etc) could include the contactless
attibute...(or biomettric like ludovic suggested)
Sending an apdu to the card, to check if that card is the "desired"
doesnt like me. Take the following example:
- Card A has an apdu 012345 which delete a file (no pin required to
delete the file :P)
- Card B has an apdu 012345 to select DF.
When looking for B DF, could I delete A files accidentaly?
