In the first instance you must contact Wireless terminal Solutions technical support on 0845 459 9984, and they will disconnect the PDQ terminal from our in-house system. Once the PDQ terminal has been disconnected it does not pose a security threat, nor can anyone process card transactions. If you have lost your PDQ machine, you can purchase a new one. Please contact your account manager immediately or email sales@wirelessterminalsolutions.co.uk.
