Re: Sounds like a non starter
"Since it is a very early trial with only a few staff at this stage all the odium appears somewhat misplaced. "
I don't think so if the report is accurate. The whole point of bonk-to-pay NFC was speed and convenience. What's described in the article is a hideously convoluted faff that seems to start from the premise that NFC has never been invented (despite compatible chips in the majority of phones shipped in the past few years). An NFC chip should still work even if the phone has too flat a battery to start, but this requires the phone up and running, an app, a mobile wallet system, possibly a mobile data connection, then the generation of a QR, optical recognition and decoding by the till and then two way interraction between till and device (to update the mobile wallet).
It's difficult to see how that's going to be sorted out. I wouldn't want a Tesco-managed wallet, in fact I don't want any digital wallet (a la Google). I don't want QR codes, and I'd expect my mobile banking app to keep me informed without being required for the transaction. All that should be needed is to register my NFC equipped phone to a Visa or Mastercard account, and for me to wave it at the NFC receptor. Those who don't want NFC needn't partake, but I hate small change, and would be delighted to see it gone forever.
