Abstract

A checkout device with a barcode reader and electronic article surveillance (EAS) system. The checkout device includes a barcode reader having substantially horizontal and vertical apertures for reading barcode labels on products, and a security label sensing and deactivation system for deactivating security labels on the products including a coil below the horizontal aperture. The security label sensing and deactivation system has a first range of operation which is increased by the EAS system by increasing field strength of the coil, or by adding a second coil adjacent the vertical aperture. An audible or visible signaling device notifies an operator that the barcode labels have been read and that the security labels have been deactivated.

Claims

1. A checkout device comprising:

a barcode reader having substantially horizontal and vertical apertures for reading a barcode label on a product; and

a security label sensing and deactivation system for deactivating a security label on the product including a coil, wherein the coil includes a housing below and adjacent to one side of the horizontal aperture;

wherein the security label sensing and deactivation system has a first range of operation;

means for increasing the first range of the security label sensing and deactivation system to a second range in order to sense and deactivate security labels positioned a predetermined height above the horizontal aperture; and

means for notifying an operator that the barcode label has been read and that the security label has been deactivated.

2. The device of claim 1, wherein in the one side is downstream of a scanning motion across the horizontal aperture.

3. A checkout device comprising:

a barcode reader having substantially horizontal and vertical apertures for reading a barcode label on a product; and

a security label sensing and deactivation system for deactivating security labels on the products as the barcode labels are being read by the barcode reader including a coil, wherein the coil includes a housing below and adjacent to one side of the horizontal aperture for sensing and deactivating first security labels within a predetermined distance of the coil;

means for temporarily increasing the distance for sensing and deactivating second security labels outside the predetermined distance of the coil; and

means for notifying an operator that the barcode label has been read and that the first and second security labels have been deactivated.

4. A checkout device comprising:

a barcode reader having substantially horizontal and vertical apertures for reading barcode labels on products, wherein the barcode reader produces a scan volume within which the barcode reader is configured to read the barcode labels; and

a security label sensing and deactivation system for deactivating security labels on the products as the barcode labels are being read by the barcode reader including

a first coil including a housing below and adjacent to one side of the horizontal aperture for sensing and deactivating first security labels within a predetermined distance of the first coil;

means for sensing and deactivating second security labels adjacent the vertical aperture and higher than the predetermined distance above the first coil; and

means for notifying an operator that the barcode label has been read and that the first and second security labels have been deactivated.

5. A checkout method comprising the steps of:

reading a barcode label on an item by a barcode reader having substantially horizontal and vertical apertures for reading a barcode label on the item;

boosting a security label detection field of a security label sensing and deactivation coil having a housing below and adjacent one side of the horizontal aperture from a first range to a second range higher than the first range above the horizontal aperture;

deactivating a security label on the item;

reducing the security label detection field from the second range to the first range; and

activating a notification device.

6. A checkout method comprising the steps of:

reading a barcode label on an item;

preventing activation of a device for notifying an operator that the barcode label has been read until successful deactivation of a security label on the item;

boosting a security label detection field from a first range to a second range;

deactivating the security label on the item;

reducing the security label detection field from the second range to the first range; and

activating the notification device to indicate that both the barcode label has been read and the security label has been deactivated.
