RFID checkout system with tags
View Patent ↗A radio frequency identification (RFID) checkout system includes a reader, a first RFID tag, and a second RFID tag. The first tag is configured to be attached to an item selected to not be read by the reader, and the second tag is configured to be attached to an item selected to be read by the reader. Upon items being positioned within the reader, the reader reads the tags to determine if the first tag is present within the reader. The reader is enabled to complete a checkout transaction if no first tags are detected within the reader during the reading. The first tag includes an attachment base, an extension portion connected to the attachment base, and a RFID antenna connected to the extension portion. The extension portion is movable relative to the attachment base between at least a first position and a second position, and the extension portion extends away from the attachment base in the first position.
1. A radio frequency identification (RFID) checkout system, comprising:
a reader for reading items;
a first RFID tag configured to be attached to an item selected to not be processed automatically by the reader;
a second RFID tag configured to be attached to an item selected to be processed automatically by the reader, wherein
upon items being positioned within the reader, the reader reading the tags to determine if the first tag is present within the reader, and
the reader is enabled to complete a checkout transaction if no first tags are positioned within the reader during the reading.
2. The checkout system according to claim 1 , wherein the first tag includes:
an attachment base configured to be attached to the item selected to not be processed automatically by the RFID checkout system,
an extension portion connected to the attachment base; and
a RFID antenna connected to the extension portion, wherein
the extension portion is movable relative to the attachment base between at least a first position and a second position, and
the extension portion extending away from the attachment base in the first position.
3. The checkout system according to claim 2 , wherein the extension portion is biased to move into the first position.
4. The checkout system according to claim 1 , wherein the first tag includes indicia indicating to a user of the checkout system that the item, to which the first tag is attached, is not intended to be processed automatically by the reader.
5. The checkout system according to claim 4 , wherein the indicia is a certain color for the first tag.
6. The checkout system according to claim 5 , further comprising a cart adapted to be received by the reader and including a first compartment and a second compartment.
7. The checkout system according to claim 6 , wherein the first compartment receives the item selected to not be processed automatically by the RFID checkout system and the first compartment includes the color that matches the color of the indicia of the first tag.
8. The checkout system according to claim 1 , wherein each first tag provides at least one output having identical information.
9. The checkout system according to claim 8 , wherein the reader determines that the first RFID tag is within the reader upon reading the at least one output having identical information.
10. A method for identifying radio frequency identification tags (RFID) tags on items selected to not be processed automatically by a reader of a RFID checkout system, comprising the steps of:
reading outputs from RFID tags on the items within a reader;
comparing each read output to a predetermined output indicating an item selected to not be processed automatically by the reader;
upon detecting the predetermined output, indicating to a user that the item selected to not be processed automatically by the reader is within the reader; and
enabling the checkout system to complete a checkout transaction if the predetermined output has not been read during the reading step.
11. The method according to claim 10 , farther comprising
determining that items to be processed automatically are positioned within the reader prior to the reading of the outputs.
12. The method according to claim 11 , farther comprising
determining that the read items having the predetermined output have been removed from the reader after the indicating to the user that the item selected to not be processed automatically by the reader is within the reader.
13. The method according to claim 12 , further comprising resetting the reader to enable the reader to read items within the reader after the determination that the read items having the predetermined output have been removed from the reader.
14. A computer program product comprising a computer useable medium including a computer readable program, wherein the computer readable program when executed on a computer causes a radio frequency identification (RFID) checkout system to identify RFID tags on items selected to not be processed automatically by a reader of the RFID checkout system, comprising the steps of:
reading outputs from RFID tags on items within a reader;
comparing each read output to a predetermined output indicating an item selected to not be processed automatically by the reader;
upon detecting the predetermined output, indicating to a user that the item selected to not be processed automatically by the reader is within the reader; and
completing a checkout transaction if the predetermined output has not been read during the reading step.
15. The method according to claim 14 , further comprising
determining that items to be processed automatically are positioned within the reader prior to the reading of the outputs.
16. The method according to claim 15 , further comprising
determining that the read items having the predetermined output have been removed from the reader after the indicating to the user that the item selected to not be processed automatically by the reader is within the reader.
17. The method according to claim 16 , further comprising resetting the reader to enable the reader to read items within the reader after the determination that the read items having the predetermined output have been removed from the reader.
18. A radio frequency identification (RFID) tag for use with a RFID checkout system, comprising:
an attachment base configured to be attached to an item selected to not be processed automatically by the RFID checkout system;
an extension portion, not attached to the item, connected to the attachment base; and
a RFID antenna connected to the extension portion, wherein
the extension portion is movable relative to the attachment base, upon the RFID tag being completely attached to the item, between at least a first position and a second position, and
the extension portion extending away from the attachment base in the first position.
19. The RFID tag according to claim 18 , the extension portion is biased to move into the first position.
20. The RFID tag according to claim 18 , wherein the tag includes indicia indicating to a user of the checkout system that the item, to which the tag is attached, is not intended to be processed automatically by the reader.
21. The RFID tag according to claim 20 , wherein the indicia is a certain color for the tag.
