Customers can get access to their bitcoins with the private key on the paperwallet they printed from the machine, but we recommend that customers setup a wallet app (Such as AirBitz) in order to store their bitcoins as the paper receipts are not meant for long-term storage (they decent ingrate over time).
- The public key is the key you give to others to send bitcoin to you. This can be posted publicly even (such as on the internet).
- The private key is the password so to say, this is the key you use to send bitcoins. You need to keep this one secret.
