My experience with London, Canary Wharf - I'm hungry but the darn Amazon app has auto offloaded. Spend 3 minutes re downloading with bad data signal. Buy sandwich. Meh - it was ok but normal check out easier for me.

Chancery lane Tesco who also had one - darn I don't even have the Tesco app, I guess I'll wait for a normal shop.

For me the system would be better if you could just tap your card like everywhere else rather than needing an app.
