Self-service checkout
First Claim
1. A system for self-service checkout of merchandise bearing a product tag including a desensitizable security tag by a customer at a retail store, the system comprising:
- a housing substantially closed to the environment, the housing defining a slot opening to an internal bay dimensioned for receiving the product tag, the housing being configured for shielding a desensitizing effect from any security tags outside the housing;
a price scanner positioned within the housing for reading price information encoded on a product tag of an item while the product tag is positioned in the bay, the price scanner being capable of transmitting the price information;
a payment card reader for reading account information stored on a payment card, the payment card reader being capable of transmitting the account information;
a payment unit for receiving the price information from the price scanner, for communicating with an electronic payment network to seek approval of a charge to the payment card, and for transmitting an activation signal upon receipt of approval of the charge; and
a selectively activatable desensitizer for desensitizing a security tag of a product tag while the product tag is positioned within the bay of the housing, the desensitizer being activated upon receipt of the activation signal transmitted from the payment unit;
whereby product tags inserted into the bay of the housing are scannable for price and the desensitizer'"'"'s desensitizing effect is limited to a corresponding security tag of the product tag scanned for price.

Abstract
A self-service checkout system allowing customers to perform purchasing functions while ensuring payment and preventing theft. The system'"'"'s payment card reader and price scanner are operable by the customer to read product tags including price and/or serial number data and a desensitizable security tag. The product tag is inserted into a slot in a housing for the price scanner and desensitizer that shields a desensitizing effect from any security tags outside the housing. The system desensitizes the security tag only if a charge to the payment card is approved. A detector is positioned near the store exit to detect items exiting the store which have not been released from the security system. Serial number information from the product tag may be read as the items leave the store and compared with a database of serial numbers of purchased items to determine whether to activate an alarm.

a payment unit for receiving the price information from the price scanner, for communicating with an electronic payment network to seek approval of a charge to the payment card, and for transmitting an activation signal upon receipt of approval of the charge; and
a selectively activatable desensitizer for desensitizing a security tag of a product tag while the product tag is positioned within the bay of the housing, the desensitizer being activated upon receipt of the activation signal transmitted from the payment unit;
whereby product tags inserted into the bay of the housing are scannable for price and the desensitizer'"'"'s desensitizing effect is limited to a corresponding security tag of the product tag scanned for price. - View Dependent Claims (2, 3, 4, 5, 6, 7, 8, 9)
an anti-theft device; and
a detector for detecting sensitized security tags present in a detection zone monitored by the detector, the detector being capable of activating the anti-theft device in the event that a sensitized security tag is detected in the detection zone.

10. A system for self-service checkout of merchandise by a customer at a retail store, the system comprising:
-
a payment card reader for reading account information stored on a payment card, the payment card reader being capable of transmitting the account information;
a housing substantially closed to the environment, the housing defining a slot opening to an internal bay dimensioned for receiving the product tag, the housing being configured for shielding a desensitizing effect from any security tags outside the housing;

a payment unit for receiving the price information from the price scanner, for communicating with an electronic payment network to seek approval of a charge to the payment card, and for transmitting an activation signal upon receipt of approval of the charge;
a selectively activatable desensitizer for desensitizing a security tag of a product tag while the product tag is positioned within the bay of the housing, the desensitizer being activated upon receipt of the activation signal transmitted from the payment unit;
a sensor for sensing removal of the product tag from the bay of the housing and preventing completion of a checkout transaction if the product tag is removed after being scanned for price by the price scanner and before desensitization by the desensitizer;
an anti-theft device; and
a detector for detecting sensitized security tags present in a detection zone monitored by the detector, the detector being capable of activating the anti-theft device in the event that a sensitized security tag is detected in the detection zone;
whereby product tags inserted into the bay of the housing are scannable for price and the desensitizer'"'"'s desensitizing effect is limited to a corresponding security tag of the product tag scanned for price.
