Why do you presume that debit card PIN numbers are stored on the card? (They aren't, as far as I know - how else could you change your PIN over the phone or on the card issuer's website?)
- chaz 13y agoSorry, I should have been more clear. PINs have not been confirmed compromised in any reports I've read so far, but it's been mentioned as a possibility. If magstripes were transmitted/stored by Target to perform the authorization, then it's possible that PINs for debit cards were transmitted/stored as well.
- joecurry 13y agoHe's not presuming the PIN is ON the card, but that the transaction was the point of compromise (i.e. you punching in your PIN and the software running a verification of if that PIN is correct).
- jakewalker 13y agoAh - that makes more sense.
