Overpayment fraud is when a criminal poses as a customer to order goods or services. They use a cheque or draft to ‘pay’, often more than the required amount, then get in contact to reduce or cancel the order, or advise that an error’s been made – and request an urgent refund in full or for the amount overpaid. The business processes the refund quickly and returns it using an electronic payment method.
In due course, the original cheque or draft will bounce, leaving the business out of pocket. The cheque could be counterfeit – i.e. a fake designed by the fraudster to look real – or forged, i.e. genuine but stolen from somebody else with the signature faked.
Alternatively, the cheque may have been altered in some way, for example the security features may have been tampered with. It might look fine to the untrained eye but would be rejected by the bank.
You can also be targeted by an overpayment scam when selling something online.
