Exit validation solutions for self-payment areas allows to ensure security in the self-check-out counter area by using a barcode. Showing an invalid receipt may start off a visual and sound alarm which will place the focus on the subject. The Validation column placed next to the exit of the self-payment area can verify whether the clients actually paid for their shopping during the minutes preceding transit so as to avoid being checked by security staff. This system also prevents users who completed payment to remain too long within the supermarket for understandable security reasons.
