It's pretty simple. The longer it takes them to use the cards, the more time you have to get them cancelled. The worst cases I've seen of credit card theft were in college. Some girls would leave their purses in their cars while in class. They would come back an hour later to find a broken window and that their card had already been used. Minutes mattered in these cases. If the thieves had been turned away at one or two stores, maybe they wouldn't have been able to use the cards.
Given the number of misinformed posts recently, I think this point bears repeating:
How does the fact that some businesses require an ID protect a cardholder when a credit card thief can simply find any number of businesses where ID is not required?
You would have to have nearly all businesses requiring ID (and violating MC and Visa rules) for ID to have any measure of protection for the cardholder.
Why do so many people miss this obvious point????!!!!
Wow.... talk about grasping at straws.........
And in any given situation, what are the odds of the scenario you describe, where there was an extremely short amount of time. They left their cards in their vehicle? How about some personal responsibility??!!!! Ever heard the statement, "Don't leave valuables locked in your car." ?
So your line of logic would go something like this:
Businesses should require ID, regardless of the objection many customers because it is their responsibility to police their customers, because some cardholders can't seem to hang onto their own card. (Granted, it is not always the cardholder's fault.)
This, despite the fact that-
1) MC and Visa rules prohibit it, nevertheless let's deliberately violate the contract the business agreed to.
2) Traditionally, no ID was required for decades until recently.
3) Much of the fraud is partly attributable to cardholder's being slack in keeping track of their cards.
4) MC and Visa have a policy of zero liability to the cardholder for fraudulent purchases.
5) Most businesses follow the rules and don't require ID, therefore in most cases it would be easily to max out a card in short order, therefore, some businesses requiring ID will be of no protection in almost all cases.
6) Many of us find the practice insulting and disrespectful and we don't want to be policed by a cashier (but hey, who cares about that?).
7) Requiring ID increases the opportunity for actual ID theft by a dishonest cashier.
Most of the above points are reason enough on their own for ID not to be required. To think that you can debunk all seven points is to be in denial.
