Thanks for the constructive feedback we will take it on board. There are a couple of points I would like to make:

1. Location aware QR codes. We considered this but the logistics of installing or mis-installing individual codes on each meter is considerable. In general we are undecided about the usefulness of QR codes for parking, vulnerability to vandalism, graafiti, etc.

2. As you are probably aware the cost to Islington to charge the cost to the mobile phone bill would be close to 30% as opposed to credit card rates of 2%. No council wants to give up 28% of their parking revenue to the mobile carrier. Happy to be proven wrong on this, will SmartPay do it for say 5%?
