Massive Security Breach At USPS

Quote:
Cash registers and point-of-sale terminals in post offices, as well as the website usps.com where customers pay for services with credit and debit cards, were not affected by the incident.

There is no evidence that any customer credit card information from retail or online purchases such as Click-N-Ship, the Postal Store, PostalOne!, change of address or other services was compromised, the service said.
