How does the post office know how much a stamp is worth?
I just bought new stamps and they look exactly like the other ones before they changed the postage
Is there a machine than scans The Stamps?
All stamps “glow” under the lights of the mail processing machines. They run through these machines at lightning speed and if you want an idea what I mean check this out
