My wife lost her purse while on holidays recently. There was almost no money in it, but her Mastercard and Maestro card were in it, as well as that little EU blue health insurance card with her PPS number on it. Although we cancelled the two bank cards immediately, and there should be no financial concerns, the purse was never handed in. Should we be concerned about identity theft, and what steps can be taken now to protect against it? I'm not even entirely sure what the consequences could be!
