Hi,
Thanks for the positive words

I haven't worked out what they cost to build as yet, still working a couple of little bugs out of the code at the moment and part of that may result in a slight change to one of the components.
Off-line mode is still under development as I have had a couple more ideas around it and how it would work, the customer can always see the exchange rate being used during their transaction regardless of the mode as it is displayed on the second screen where the FIAT value is entered, they also get to see the total number of FTC being used for the transaction on the QR Code screen so there are a couple of options for the customer to re-evaluate the purchase.
I have agreed with the Oxford Blue that they can have a device once we have closed down a couple of things for a trail, after all it was there where I spent my 1st feather coins and got the idea for this from having watched their staff struggle with a laptop on the bar
UM
