Does it say 'enter password to renew Touch ID'?
Unfortunately, I think it has the same restriction as unlocking the phone. If you haven't used it for 48 hours (in the Store, I mean) or you've restarted, you'll have to use your password for your first purchase. After that, it should ask you to scan your fingerprint after you press Buy or Install. I think if you don't download things frequently, you'll never be able to use Touch ID.
Try it now with a couple of free apps.
