- a counter detacher system 50 may be used as a means for self- check-out at a point-of-sale system (see, e.g., FIGS. 7-8).
- a customer may be authorized to use a counter detacher system 50 in order to remove a security device 16 from an item of merchandise at the time of purchasing the item. In this way, a customer does not have to wait for a sales associate to remove the security device 16, and the presence of security devices may deter customers from otherwise using self-check-out lanes.
- the electronic key 12 may be authorized to remove a security device 16 at check out after the customer makes the purchase.
- the point of sale terminal 52 may either automatically recognize that this particular item of merchandise includes a security device 16 (such as in response to scanning a barcode on the item of merchandise, security device, or sales receipt), or the customer could be prompted to indicate whether a security device is present. If a security device 16 is detected or present (either before or after purchasing the item of merchandise), the point of sale terminal 52 could authorize the electronic key 12 for removing the security device. Upon removal of the security device 16, the customer may be instructed to discard the security device or place the security device in an appropriate receptacle 54, such as for reuse by the retailer.
