We’ve done this several times in GQ, but just to recap:[ul][li]Credit card companies have something called a “floor limit,” which is an amount below which they don’t require a signature. The limit is generally merchant- and industry-specific, but it’s generally in the neighbourhood of $50. There is a grocery store in Tokyo, for instance, that has a 20,000 yen (~$180) floor limit.“Card-not-present” transactions (such as mail order or Internet purchases) have more stringent risk management requirements. However, when there is a physical manifestation of a transaction (such as a book or CD that gets mailed to you), it’s much, much harder to get away with charging it back.[/ul][/li][/QUOTE]
This has not been communicated to me either as a clerk then manager for Blockbuster, nor as a small business owner taking credit cards. Maybe it’s different in the US.
Under normal, not disputed conditions, the credit card company never sees those little slips you sign. Only if you dispute a charge do I make a photocopy of it and send it to them.This means I have to go digging around and find the charge slip from six months ago. It’s much stronger proof if the customer’s signature is on the charge slip. But, like the furst reply said, it’s probably not cost-effective for McDonald’s to pay someone to go digging into their paper reciepts to dispute a chargeback. Even if it only takes an hour, they’ve paid them $6.75. They’d rather eat the $5.78 charge.
The pharmacy, OTOH, has proof of transaction in a much easier to access place: their computer. Walgreens has you sign on the touch screen to signify that you’re gotten your prescription, and the computer has the payment method info in it already. So they present your electronic “I got my meds” signautre as proof that you authorized the charge. Other pharmacies make you sign on a label or a clipboard for your meds - either way, it’s all the proof they need, without having to sort through eleventy thousand paper slips for each chargeback.
I do wonder about gas stations, though. Do they rely on security cameras to snap a photo of each license plate and time stamp it?
