Hi,
Can anybody kindly explain to me how dumps work with nfc please?
I really want to know how it works. Is it like you use a application to write the track 2 dumps onto a NFC then you can use it as tapping your card? If so which application or software will I use? I’m also very confused with how to use this with AirPay it Mywallet?
Does this method work with Canadian domestic cards?
Any tips or hint will be very appreciated.
Thank you all,
