Smart Postage Meter 

A postage meter or franking machine is a mechanical device used to create and apply physical evidence of postage (or franking) to mailed matter. Postage meters are regulated by a country's postal authority. ... A postage meter imprints an amount of postage, functioning as a postage stamp, a cancellation and a dated postmark all in one.

• Feeder (sends envelopes through the meter)
• Postage Scale (which weighs postage)
• Sealer (moistens the flaps of envelopes)
• Stacker (stacks envelopes)
• Tape Dispenser (when postage cannot be printed directly on the mail piece)
