On: We’re adding barcodes to our regular stamps

To the HN crowd... This is the risk of any kind of token that has no expiration date.

If whatever security measures you have in place ever get broken (watermarks, holograms, digital signatures, etc), then you have a big problem.

And no security feature available today will be secure forever.

So your company or government should never issue digital or real tokens that last forever.
