HMRC have introduced card readers for when they carry out face to face visits regarding debt. Previously the HMRC customer would need to call the HMRC helpline to make a payment. HMRC are hoping this move will help reduce the calls through to the helpline, giving more capacity for HMRC customer queries.
HMRC customers will of course need to be very careful that the person visiting their premises is a HMRC staff member. The HMRC website provides information on how you can verify whether the person is a HMRC employee. There is also a number you can call HMRC on to check, 0300 200 3862.
