In Taiwan 10 years ago, they had checks, but instead of signatures they used "chops" -- an ancient Chinese identity system based on small square stamps with the characters for your name carved in them. The ink is red. The system is thousands of years old, but was still used in an advanced Asian democracy for checks, receipts, and practically anywhere else you might use a signature (except for passports). I even had one (made out of metal, I still have it lying around somewhere) even though it was based on a Chinese name I made up in Mandarin class. I mostly used it for accepting registered mail and "signing" some official documents, but for other types of transactions they had foreigners use their real names and scrawled signatures.

They're still used there, google chop stamp taiwan and you'll get a bunch of results.

And yes, chops can be forged, and when I was there, there were many criminal cases involving forged or stolen chops.
