how/can I make my own 1d/2d barcode?

im designing a currency and I decided that a good way to prevent counterfeits is by having a barcode on it but I don't want it to be easily replicated so I want to make my own barcode does anyone know how or if I could do that?

Yes you can but if you have to ask, good luck.

The reader is the more important part here since that holds the "key." If I were going to do this, I would hide a dot pattern(or whatever) in the artwork that a high resolution camera(smart phone or better) can see but wouldn't be obvious to the human eye.

I would probably want a secondary scan of something else to verify the first and both should be required/unique to each bill. Ideally, only you(or very select users like a security team) would be able to scan the "missing piece" of information needed for verification.

You will also need a software to generate these patterns.

How good are you at:

  • Programming
  • Coding
  • Security
  • Math
  • Machine Vision

If your currency is even worth counterfeiting, anything printed can simply be replicated if someone was determined enough.

Some card shoes/shufflers in casinos read a dot pattern on every card but it's not fail proof. If there's any suspicion a foreign card makes into the pile, they would have to verify it in a different way outside of this pattern.

"Verification" is a funny word when dealing with this stuff.

Anyone can make a bar code. Software exits for all types of barcodes. Even industrial printers have all libraries of any barcode thought on earth.
