FeatherCoin - featherPay - Point of Sales Device

One of the things I noticed very early on was how complicated it was for merchants to accept feathercoin for goods, others on the forum wrote a guide on how to do it but it all seemed very long winded and a little too complicated to me, this coupled with going to a few meet-ups at the Oxford Blue and watching the bar staff have to deal with a laptop on the bar to allow us to pay with our favourite crypto currency. The cogs started to turn as they do and this is what I have come up with.

A simple and easy to use handheld payment terminal that merchants can use to take payments via feathercoin for any goods or services that they sell or deliver, how easy would it be for these people to accept feathercoin if all the technology was wrapped in a simple handle held device?

So how does it work?

Quite simple really, there are 4 steps to each transaction

1. Obtain the current value of feathercoin

2. Tell the device the transaction value

3. Present a payment QRCode for the customer to scan

4. Display confirms for the transaction

featherPay is designed with 3 connectivity methods in mind

WiFi

Everything takes place in real time, every time a transaction is started the current exchange rate is obtained via the network connection, once the transaction has taken place the merchant can get a visual on the number of confirms for the transaction. Aimed at the corner shop, pub, coffee shop etc..

3G

Exactly the same as operating in WiFi mode, but with the added advantage of not needing the WiFi connection. Opening up a greater choice of locations for feathercoin merchants. Aimed more at the market trader, street vender type of merchant.

Off-Line

Prior to the trading day, the merchant can obtain the current exchange rate and this is saved to the device, when the trading day is finished the unit is connected to WiFi and all transactions throughout the day are processed. It goes without saying that step 4 from above does not work in this mode as there is no network connection to obtain the confirms against the payment address from. Again aimed at the market trader and street vendor type of merchant.

Input into the payment terminal is via both a touch screen display and the small number pad, for most actions you tap the buttons on the touch screen and for transaction values you input the value using the number pad.

Transaction Walk Through

The payment terminal constantly displays a simple start screen advertising the fact that feathercoin is accepted by the merchant

When the merchant taps the screen, the terminal moves onto the second screen displaying the current value of 1 FTC and the ability to input the transaction amount in the local FIAT currency

Tapping the “Process” button moves the terminal on to the 3rd screen creating a unique wallet address and a corresponding QR Code for the transaction ready to be scanned by the customer using the wallet application on their mobile phone. Also displayed is the total number of FTC required for the current transaction. Tapping “Cancel” causes the terminal to terminate the transaction and return to “feathercoin ACCEPTED HERE” screen

Once the QR Code has been scanned, tapping the “Confirm” button displays the final screen in the sequence which allows the merchant to check on the confirmed status of the transaction from the blockchain. Again tapping “Cancel” causes the terminal to terminate the transaction and return to “feathercoin ACCEPTED HERE” screen

The “New Transaction” button simply stops the background confirm checking process and returns the terminal to the “feathercoin ACCEPTED HERE” screen, ready to start the process again for the next customer.
