The Bitcoin Fluid Dispenser II and 2.3



I've developed a prototype retail diesel fuel dispenser that accepts bitcoin for payment. You can learn more about this device by watching the videos below. I'd also encourage you to read about "The Original Bitcoin Fluid Dispenser" and watch the demonstration video that I created, as there is additional description about the practical and ideological motivations for the technology as well as additional use cases.

The Bitcoin Fluid Dispenser 2.3 - Technical Demonstration Video


The Bitcoin Fluid Dispenser 2.3 is an improvement of The Bitcoin Fluid Dispenser II that includes Near Field Communication (NFC), Bluetooth communication, and the bitcoin payment protocol. Using the bitcoin payment protocol with a Bluetooth connection allows for payment to be made with no internet connection on the customer's mobile phone or tablet computer.
