Planning.
You're joking, right? Less than a year to go and the entire payment system is still up in the air? You have "Paywave" only terminals that, as of today, not one person can PayWave on at all? And the only alternative strategy is PayWave microSD's that don't always work through mobile phone cases?
Can I please get a front-seat ticket to the fights at the venue's payment stations, or do I have to have a Visa card for that?
