How does Airbitz use Bluetooth (BLE) with Bitcoin?

The Airbitz wallet uses Bluetooth Low Energy (BLE) to transmit the requesting user’s public address and requested amount over the air in replacement of displaying a QR code. This is currently compatible only on iPhone 4S and above using iOS versions 7.0 and higher.

The requesting wallet transmits the first 10 digits of the public address and the optional name/handle of the user. The sender will detect the name and display it in a list of other requests on the Send screen. Should more than one request have the same name/handle, the request will be highlighted in orange as a warning for the user to double check the address prefix before sending funds.

The sending user need only tap on the request, and they are brought to the Send Confirmation screen where they can change the amount and send off the bitcoin transaction.
