I have seen contactless card payments "failing" multiple times even

in the past month. Once was someone who paid for a meal at a restaurant, tapped his card and went to sit back down at his table, only for staff to come over later and explain the payment didn't go through. Another time, a shopkeeper ran after someone who had left the store, without the payment confirming. Things like this surely happen all the time, and for very simple reasons like the customer just not having enough money in their account. BCH doesn't have the same problem. We can see immediately whether or not there is enough money, and that the transaction is generally valid. Why are we even considering adding delays to protect against highly sophisticated, difficult and expensive fraud, when our main competitor is already doing a far worse job?

people greatly overestimate sophisticated fraud risk in physical retail. IRL either you're not gonna risk anything because your very vulnerable-to-jailing person is there, or if you no longer care you'll just walk straight out with the loot as happening in some places. there's not a lot of room in between.
