Very true. Our goal is slightly different, because we are trying to completely remove the counter-party risk of having someone else create and be in control over your public + private key at any point. Now I'm no computer whiz, but after consulting with nerdier friends of mine, I believe it is possible to develop an app that can create a public and private key, and transfer those keys to an NFC chip. This would mean we could sell the NFC chip / Physical Bitcoin, and the customer would be able to create and export the private/public keys on their own. Thus, customers would not have to trust us and our ability to keep their keys a secret (or steal them ).
