It happened to me once, and had to pay again to get it
Why don't epassporte use USPS service? I think it's cheaper than UPS or Fedex, and much better than regular mail!! at least it won't get lost!
There's always been a lot of mail theft!!
I remember once back in 2001 (I live in Buenos Aires), and I was expecting a check that was sent from Albuquerque, New Mexico, and someone cashed MY check in Pensylvania. The company sent me copies of the cashed check, WTF?? Needless to say they didn't pay me again.
Some other time I received a phone call from a local bank, and the guy who works there knows me, so he tells me that someone with a fake ID was trying to cash a check under my name.
That's why I hate regular mail, and you should stay away from using it. Maybe for sending a postcard, but not checks or debit cards!!
