A little warning: if you use Apple Pay, this is secure and safer than carrying a bank card.
But it also allows very large amounts to be taken from your linked cards, vastly exceeding their usual limits.
Our bank tells us that Apple Pay transactions are not as scrutinised as other systems, because of the security. This has a downside.
My daughter was accidentally charged £4,400 for a burger and chips this week. The shop accepted their error today. Others might not.
