I submit to it, but I don't feel safer because of it.If anything, it has the opposite effect of making me think we're all doomed because we're so clueless and easily manipulated.• December 8, 2006 PM Yes, put the serial number under a scratch-off coating...
A PIN could protect against this, but only if it is not guessable given the serial number.
• December 8, 2006 PM This is a new version of an old scam.

(Stealing an unactivated one just gets you a piece of plastic.) Most stores use the optical-scan bar code.

Does anyone have a list of gift card manufacturing companies on the two sides of this matter? By manufacturer I don't mean Home Depot, etc, I mean whoever it is that supplies their gift cards.

The attacker starts by buying one card, and working their way down the list of possible numbers in sequence.
Seems they take the cards off the racks in stores and copy down the serial numbers.
