We can't go anymore, first, tickets are expensive, like starting at $200-300 in Canada. Then the minute they go on sale, they are all sold to scalpers who resell them $2000 on kijiji. Madonna tickets reached $6000.
So I stopped caring about live concerts.
In Canada it's tap to pay for ~8 years now, never saw a QR code to pay. However when I go in USA, every stores is tap to pay, except one, there's one store in USA where there is no tap, it's Walmart, inconcevable.
