Counterfeiters Kill Subway Stamps

I had no idea losers were selling Subway stamps on eBay or just plain counterfeiting them. Now Subway will end the program. This is a good example of reacting to a changing threat environment. When the stamp program was started in the 1980s, I imagine the majority of the users were honest and the technology to mass-produce look-alike stamps wasn't accessible to most people. Throw in high-quality printers and unscrupulous employees who steal and sell stamps, and we end up with the current situation. Perhaps Subway will institute some sort of electronic rewards card to replace the stamp system?
