The mobile point-of-sale (mPOS) technology now being tested in 50 Post Offices around the country has been well received by customers and the media.

During the holiday season, facilities testing mPOS processed more than 102,000 transactions using the technology. The system consists of three pieces of equipment — an iPod hand-held device, a portable receipt printer and a postage printer.

With mPOS, lobby assistants can greet and assist many customers with simple transactions, allowing them to “swipe and go.” They also can scan and accept prepaid packages, scan package pickups as delivered, or sell stamps, ReadyPost and other retail products. Retail associates also can use mPOS to sell Priority Mail flat-rate postage.

A retail associate accepts payments with mPOS by swiping credit cards and non-PIN debit cards. A customer can choose to accept a hard-copy receipt or have one emailed to a personal email address. source: USPS
