I think the problem could be mostly solved by requiring people who are getting credit to apply somewhere in person. Most credit card banks have branches everywhere (USA). The person has to have their face recorded stored along with credit line. This would have many benefits: legitimate people would think more about how serious getting a credit card is, fraudsters would be less likely to try and get fake credit, and it would be much clearer when the bank gave credit to the wrong person and has to eat the loss. Unlike the past, taking and storing pictures is now a trivial task. This is not likely to happen as the credit companies little liability under the current system.
