Hallo Shekhar, if the card supports ISO 14443-4 (which every EMV card should do) you can access this card with APDU commands through ISO-DEP. (* Except for some cards that seem to require a higher magnetic field strength than the Nexus S provides.)
Using APUD commands you can then access whatever information the EMV standards allow you to access. br, Michael On 14.06.2011 08:37 Shekhar wrote: > Hi Michael, > > I have a doubt.You mean to say that if the EMV card supports ISO 14443 > standard then we can be able to read the payment details of the credit > cards using APDU commands? > > Thanks, > Shekhar > > On Apr 25, 5:09 pm, Michael Roland <mi.rol...@gmail.com> wrote: >> Hallo lal, >> >>> I'm trying to Read Track data for Payment cards (PayWave, PayPass).
