Product Description

Fully customizable: Your own QR code + choose a logo for the back side: Bitcoin, Litecoin, Dogecoin, Ethereum, Storj, Counterparty, Monero, OR your own (simple) logo. Just take your pick in the ordering process.

This item came out of a need that I felt I had for myself. Or, feared I would one day have without being able to fulfil it.

The fact that the Bitcoin network is Internet based has the downside that it doesn't work without a piece of technology, such as your computer or mobile phone. So what if, one day, I was away from my computer, my mobile phone just ran out of juice, and I needed to take a Bitcoin payment from someone?

A physically printed QR code that I always carry on me would solve that, of course. But a QR on a piece of paper folded in my (analogue) wallet just doesn't cut it on the nerd coolness scale. A QR code engraved in a 3D printed stainless steel keychain does, however. I always carry my keys with me. Attach my emergency Bitcoin QR code to my keys, and I always have my QR code with me. Of course, as multiple use of one Bitcoin address is discouraged, this is not for everyday use, but for that few times where I can't take a payment in any other way. Sort of an insurance, if you will.

When ordering this QR code keyring, you will be asked to provide a Bitcoin address. I will generate a QR code containing a "bitcoin:" payment request with your address in it and model it into the keychain model that you see in the photos and then let Shapeways print it and send it to you. This way you will get your very own customized and unique Bitcoin keychain. You can also add another text that I will encode as a QR code.

Note: In order to maximize readability by a QR reader, it is adviced to spray paint the QR side of your keychain in black and then polish off the paint, so as to improve the contrast between the dark grooves (where the paint stays after polish) and the lighter tops. Also, the keychain will often arrive from Shapeways with polishing rubble stuck in the grooves of the QR code. These need to be peeled out with a needle or similar.
