How do identify an Arduino counterfeit?

How does the Post Office identify counterfeit stamps?

  • So I was mailing off a letter, and I was thinking, "man, there are a billion different stamp designs out there. I could easily take any picture and print it out on a blank sticker and mail it off." Ok, obviously that would be Mail Fraud and therefore a Federal Offence not worth committing, but wondering if the post office really has any way of identifying fake stamps. They don't seem to be encoded with any anti-counterfeit designs.

  • Answer:

    I think that they are printed with something invisible to human eyes but that the machines read. This would cost less than having a human check to see if the letters have the correct amount of postage, and would be harder to counterfeit.

In the U.S., postage stamps are protected by the Information Based Indicia (IBI) technology. IBI is an encrypted 2-dimensional bar code that makes counterfeiting more difficult and easier to detect. Each IBI is unique. It is machine-readable.

Yes there is a way for postal machinery to identify valid postage. But if I told you how, I'd have to kill you.
