Well over 10 years ago Chip and PIN (no signature ever needed) became the norm over here to cut down on fraud but if the physical card was stolen along with the address of the owner then it is still possible to have it used fraudulently online.
Our daughter moved back to England recently and opened a bank account with Chase UK. She received her debit card a couple of days ago and it has no numbers printed on it at all. When she went online using the Chase app to activate it and it gave her the option to add it to her iPhone so she can pay with Apple Pay. The app shows the card number also has the CCV security code for her to use it online. Another step towards reducing fraud.
