Abstract

Embodiments of the present invention are directed to systems and methods for conducting purchasing transactions using radio-frequency identification (RFID) of items for purchase. Such systems may include a security scale integral with a security conveyor for weighing one or more items placed thereon, a bagging area, a second conveyor for transporting items from the security conveyor to the bagging area, a lane controller for carrying out a purchasing transaction, payment means for accepting payment for the transaction, an RFID reader for receiving data from RFID tagged items and a database having item information stored therein. The system may write new information onto the tag. The system may utilize tag data for item validation and amending an item profile in a security database.

Claims

1. A self-checkout system comprising

a security area for recognizing a item characteristic;

a lane controller for carrying out a purchasing transaction;

payment means for accepting payment for the transaction; and

an RFID reader for receiving data from RFID tagged items.

2. The self-checkout system according to claim 1, wherein the security area comprises a scale for weighing one or more items placed thereon.

3. The self-checkout system according to claim 1, further comprising a security conveyor including an integrated scale for weighing one or more items placed on the conveyor.

4. The self-checkout system according to claim 3, further comprising a second conveyor for transporting items from the security conveyor to a bagging area.

5. The self-checkout system according to claim 1, further comprising a database having item information stored therein.

6. The self-checkout system according to claim 1, wherein the RFID reader is capable of reading at least one RFID tag.

7. The self-checkout system according to claim 1, wherein the RFID reader is capable of accessing, rewriting information and/or writing new information onto at least one RFID tag.

8. The self-checkout system according to claim 2, wherein the RFID reader is integrated with the scale.

9. A method for conducting the purchase of items using a self-checkout system comprising:

providing a self-checkout system comprising a security area for recognizing a item characteristic, a lane controller for carrying out a purchasing transaction;

payment means for accepting payment for the transaction and an RFID reader for receiving data from RFID tagged items;

receiving item information from an RFID tag of an item that is passed proximate the RFID reader; and

transferring the item information to the lane controller for processing the transaction.

10. The method according to claim 9, further comprising transferring second information to the RFID tag from the self-checkout system.

11. The method according to claim 9, wherein the item information comprises an item identification code and wherein the method further comprises accessing an item lookup table to find at least one of item price and item security characteristic.

12. The method according to claim 11, further comprising entering the item price into the transaction and comparing a measured security characteristic value of the item with the item security characteristic from the lookup table.

13. The method according to claim 9, wherein the item information comprises at least one of an item price and an item security characteristic.

14. The method according to claim 13, further comprising entering the item price into the transaction and comparing a measured security characteristic value of the item with the item security characteristic obtained from the RFID tag of the item.

15. A computer readable medium having computer instructions provided thereon for performing a method for conducting the purchase of items using a self-checkout system, the method comprising:

providing a self-checkout system comprising a security area for recognizing a item characteristic, a lane controller for carrying out a purchasing transaction, payment means for accepting payment for the transaction and an RFID reader for receiving data from RFID tagged items;

receiving item information from an RFID tag of an item that is passed proximate the RFID reader; and

transferring the item information to the lane controller for processing the transaction.

16. A computer application program operable on a computer system of a self-checkout system for performing a method for conducting the purchase of items using a self-checkout system, the method comprising

providing a self-checkout system comprising a security area for recognizing a item characteristic, a lane controller for carrying out a purchasing transaction, payment means for accepting payment for the transaction and an RFID reader for receiving data from RFID tagged items;

receiving item information from an RFID tag of an item that is passed proximate the RFID reader; and

transferring the item information to the lane controller for processing the transaction.

17. A self-checkout system comprising

a security scale integral with a security conveyor for weighing one or more items placed thereon;

a bagging area;

a second conveyor for transporting items from the security conveyor to the bagging area;

a lane controller for carrying out a purchasing transaction;

payment means for accepting payment for the transaction;

an RFID reader integrated with the security scale for receiving data from RFID tagged items; and

a database having item information stored therein.
