I thought at the beginning contactless could only be used three times a day and any other transactions you'd have to use your pin. Not so as I spent an afternoon in a pub using my (his) card numerous times.
I thought they were pushed to everyone to reduce security and potentially cause stress and worry for the customer. I see no convincing reason for them to exist and no excuse for sending them out as default.
Of course Svejk. If I have the card it's because he's given it to me. I'm not a shopaholic and I'm not carefree with money plus my wages get paid into his bank account.
