Abstract

An indicia reader system includes an indicia reader provided at a point of transaction; a controller for controlling power to the indicia reader; a detector for detecting a customer, item or shopping cart at the point of transaction and providing an indication signal to the controller of the presence of customer, item or shopping cart at the point of transaction; wherein the controller interrupts power to the indicia reader during a power save mode and resumes power to the indicia reader upon receiving the indication signal.

Claims

1. A system comprising:

an indicia reader provided at a point of transaction;

a controller for controlling power to the indicia reader;

a controller that interrupts power to the indicia reader during a power save mode and resumes power to the indicia reader upon receiving an indication signal;

a first detector for detecting a customer, item or shopping cart at the point of transaction and for providing the indication signal to the controller on the presence of a customer, item or shopping cart at the point of transaction being detected using the first detector;

a second detector comprising a photo detector for sensing items disposed on the bottom of a shopping cart and for providing the indication signal to the controller on the presence of a shopping cart at the point of transaction being detected using the second detector, wherein the first detector is disposed at the indicia reader and wherein the second detector is disposed at a location spaced apart from the indicia reader.

2. A system according to claim 1, wherein the first detector comprises a photo detector disposed on a side of the scanner facing the customer.

3. A system according to claim 1, wherein the photo detector of the second detector is disposed at the entrance of a point of transaction checkout lane.

7. The system of claim 1, wherein the system further alerts an operator of the existence of an item on the bottom of the shopping cart.

4. A method of operating a system comprising the steps of:

providing an indicia reader at a point of transaction;

controlling power to the indicia reader during a power save mode to interrupt power to the indicia reader;

detecting a customer, item or shopping cart at the point of transaction and providing an indication signal to the controller of the presence of the customer, item or shopping cart at the point of transaction;

resuming power to the indicia reader upon the controller receiving the indication signal;

wherein the detecting comprises using a first detector and a second detector, the first detector for detecting a customer, item or shopping cart at the point of transaction and for providing the indication signal to the controller on the presence of a customer, item or shopping cart at the point of transaction being detected using the first detector, the second detector comprising a photo detector for sensing items disposed on the bottom of a shopping cart and for providing the indication signal to the controller on the presence of a shopping cart at the point of transaction being detected using the second detector, wherein the first detector is disposed at the indicia reader and wherein the second detector is disposed at a location spaced apart from the indicia reader.

5. A method according to claim 4, wherein the first detector includes a photo detector disposed on a side of the indicia reader facing the customer.

6. A method according to claim 4, wherein the photo detector of the second detector is disposed at the entrance of a point of transaction checkout lane.

8. The method of claim 4, wherein the method further comprises alerting an operator of the existence of an item on the bottom of the shopping cart.

9. The method of claim 4, wherein the method further comprises displaying an image of an item on the bottom of the shopping cart.
