E-Stamp Inc, which last March became the first company to receive approval from the US Postal Service for its Internet Postage system to print postage value on bar codes, will today announce what is described as a major partnership to enable it to begin selling postage online for the first time. No further details were available, but E-Stamp was due to begin commercial rollout of its system by the year end, embedding it into software such as word processors and other applications, with a version to be used through a browser still awaiting approval from the USPS (09/01/98). The service is aimed at small businesses. E-Stamp’s investors include AT&T Corp, Compaq Computer Corp and Microsoft Corp.
