The UK is using offline PIN for the forseeable future. That is, the connection to the bank will only be used to authorise the transaction where needed - the PIN verification will be performed by the card.
The card generates a cryptogram. The cryptogram contains the information necessary to instruct the terminal to authorise/reject/refer the transaction.
