With so many retailers using Square and iZettle, how about a Monzo integration. It would be similar to the Flux integration and it would work like this:
•When Square/iZettle send their email receipt, they also send the receipt to Monzo (opt in, of course).
•Monzo pulls the transaction details (ie i bought a cappuccino and a chocolate bar).
•Monzo correctly autopopulates the retailer name and logo information.
Considering how many more retailers use Square and iZettle than Flux, this could really be a game changer.
