Pitney Bowes starting to test their self service kiosk stating late 2005. The first generation of kiosk will print thermal stamps with mail type in various denominations with indicia matrix at left and USPS eagle head at right. In Nov 2011, PB  started to test the second generation of kiosk, which can print both thermal stamps of 1 and sheetlet of 10. The design of thermal stamps also change: the indicia moved to the right and eagle head logo moved to the left. However, if the location of kiosk is not owned by USPS, there is no Unite States Postage and Eagle head.
