Thinking about easing use of BTC just two days ago I thought why nobody has introduced BTC certificates that would act like Cassius coins but be just paper and disposable if you wanted to 'redeem' them digitally. The note would be like a scratchcard that had a QR of a public address so that you could verify that it hasn't been spent with a quick scan of the BitScan or similar app. The private key would then be under a tamper proof seal with a signature from the issuing company on the front to verify it isn't fake.

Once enough of these in various denominations are in circulation people would begin to see that they can't be faked and will get used to trusting their value without bothering to verify that the address contains the balance. You then have circulating cash that needs no technical knowledge, just the old school wisdom of spotting a fake and not letting people nick your real wallet.

It was only hours after I had this thought that Max Keiser started tweeting about Prypto cards that seem to be several steps ahead of me. Searching on here it seems only the germans are onto this. Any reason why there's less talk of a cash form in English?

The only problem I see it how the issuing company makes a profit enough to cover the risks but I guess Prypto has a plan.
