Is the check REALLY in the mail?

This week in PostalWatch News we found the following article.  This could become a valuable tool to track your mailings.  Have you seen envelopes with the new tracking capability?

CHECK IN THE MAIL?  POSTAL SERVICE READY TO TELL YOU WHERE
If the U.S. Postal Service has its way, "the check is in the mail" excuse will no longer be valid.  The company that sent you the bill could verify whether you're bluffing through a bar code on the return envelope scanned by the Postal Service. 

That tracking system, which starts this month, is one way the Postal Service is making first-class mail such as bills and personal correspondence more valuable, in a world full of e-mail and electronic documents.  Meanwhile, the red, white and blue may just become a serious competitor to brown-United Parcel Service-in small-package delivery.  The Postal Service says a financial institution will test the system in July by using the new bar code.  The customer will track mail as it winds through the Postal Service's 283 processing and distribution centers across the country.  Currently, mail is mostly scanned at the beginning and delivery points.  By year's end, all letter mail could be tracked at Postal Service facilities.
