A positive pay system is a measure by the RBI to prevent frauds perpetrated through cheque payments in the form of tampering or alteration of the cheque. The drawer of the cheque reconfirms key details of the cheque which can then be cross-checked at the time of presentation of the cheque while processing the payment. If the cheque details provided through positive pay match with the details of the cheque presented, the payment is processed, else, the cheque is returned.
