- Once upon a time I worked for a bank. I read a report estimating
- losses on credit cards from fraud vs. other causes, as well as
- detailing some of the security measures on today's cards.
-
- The long and the short of it is: Losses due to fraud are currently
- an order of magnitude less than losses due to simple non-payment
- of what's owed.
-
- Until fraud becomes a more significant problem, there is little
- motivation to invest resources into reducing fraud when the same
- resources could be used to try and reduce non-payment of debts.
-
-
- At the same unnamed bank, we were required to use smart cards for
- some things, and heavily encouraged to use them in some pilot
- customer-type projects. This was two years ago, and maybe state
- of the art has improved, but the smart cards we were using had a
- lot of reliability problems (chip popping out of card, not working
- after you sat on your wallet, not surviving exposure to water,
- etc.). Customers already get very upset when their mag-stripe
- cards stop working, and replacing them with something that is much
- more fragile doesn't seem like a good idea.
-
-
- So smart cards are likely to be delayed until costs fall nearer to
- the costs of making a mag-stripe card, and reliability increases
- to a level similar to a mag-stripe card.
-
- Or until fraud becomes a more serious problem...
