2. device-to-device transactions over bluetooth
Doing off-line BC transaction over bluetooth devices during the
day and sync the transactions to the BC network with
internet-connected computer later.

What do you think folks?

So, decided to replace Bluetooth to screen barcodes? Sad

Suggestion (from this topic):

"Bitcoin debit card"

Bluetooth wireless 'smartcard' device which can ECDSA cryptography. On PIC controller with LCD screen and 2 buttons.
It can receive request (bills) for payents by bluetooth, display payie selfname and "To: payee address", amount and wait for pushing 'Pay' or 'Cancel'.
Bluetooth connection are encrypted by assymmetric encryption without certificate (it is not needed because device have a display with buttions).

I dreamed a such device today. It is been cool green PCB in the glass box. Unfortunately, firmware and source code not copied from dream

If it is interesting can discuss the details. For example, which opensource protocol implementation can be used for communication via bluetooth?
