Speaking of competing standards. I have this Visa "blink" card from Chase. The supermarket where I shop, has terminals that accept "blink". Guess how often can I use my card there? The thing works maybe once in ten times I actually am trying to pass my card over the sensor. It's just easier to swipe it in the first place.
I wonder how people used to M-Pesa cope when outside of Kenya and the other countries where it works.
