Hi Shawn,

I was looking at your website and couldn't find any contact information. How do we contact you if we have a problem with a transaction at the machine?

I ask because a couple of weeks ago I had a problem at a machine in Toronto and the owner of the shop the machine was in had no idea of anything to do with bitcoin or the ATM; luckily we were able to get a local rep from the company that owned the machine on the phone and he walked us through correcting the problem.

It appears I should have received a string of about 34 characters, not 16. I'll assume that if the screen hadn't timed out before I finished writing the characters down and hit the * key it would have given me a second screen with the additional information. It's a problem with the ATM if it doesn't have controls built in to ensure a transaction is successfully completed.

Unfortunately, the store with the machine closed shortly before I went back. I'll go back tomorrow to talk to the store owner.

Thanks for your reply. When I do that I get the error message "Error importing private key: unknown key format"

Also, if that was a public key don't I also need the public key to add the bitcoin to my wallet, or am I misunderstanding it?

I bought some bitcoin at an ATM today.  A couple of moments after inserting my money the display on the ATM asked if the paper wallet printed correctly, it didn't (nothing came out) and so I pressed the key it said to press if it didn't print. It then displayed a string of 16 alpha-numeric characters with the message I should write them down or take a picture of them. I took a picture then decided to write the string down in case the picture was blurry. When I was half way through writing it the screen went back to the welcome string.

I'm not sure what to do with the string of characters. I tried entering them into a qr code generator, but my wallet told me it wasn't a valid bitcoin address. I thought I should have received two strings: a public address and private one. Is that right? If I did receive all I need how do I enter this string to my wallet (blcckchain.info) to receive the bitcoin?
