In Interlock mode, if a barcode cannot be scanned, the operator must manually enter the barcode data. After entering the data and pressing the EAS button, the operator has 3 seconds to present a soft tag to deactivate.
If a barcode is scanned but the tag was not deactivated, the operator cannot pass the item through the deactivation area a second time to deactivate the tag. This would decode the barcode a second time, charging the item twice. Instead, after pressing the EAS button, the operator can present a soft tag for deactivation within the next 3 seconds without re-decoding the barcode.
