Printing Security

It is obviously illegal to photocopy banknotes and to try to pass the copies off as real. In any case, notes are designed especially to thwart attempts to do so, relying on printer technology limitations and using features that will not copy well, and also using special paper.

It seems to me that the rest of business is not keeping up so well. While big stores sell reasonably secure gift wouchers, many also give out discount vouchers that appear to be on standard paper , easily copyable, with no obvious security at all. While some vouchers are intended purely as an incentive and the sale will still cost in even if the voucher is cashed, some are more of a reward type
and would make a loss for companies if too many are used. As copiers get better and better, this risk will grow.

However, it is now possible to print electronic components and circuits using special inks in conventional inkjet printers. It is surely time for companies to start using such technology to print vouchers that are partially electronic. These will not be so easy to copy or forge. Even simple inductive circuits would be a big improvement in security compared to the dumb vouchers of today. Certainly, for gift vouchers and higher value items, it is time to start using smarter paper by printing electronics on it.

Not that I would ever think of taking advantage.
