Abstract

A method of verifying the authenticity of an identification card, including capturing, with a point-of-sale scanner, a first image of the identification card, configuring an ultraviolet filter mounted within the point-of-sale scanner to allow the passage of ultraviolet light within, illuminating the identification card with ultraviolet light, capturing, with the point-of-sale scanner, a second image of the identification card, and determining if the identification card is authentic by analyzing the first and second images.

Claims

1. A method of using a point-of-sale scanner, the method comprising:

capturing, with the point-of-sale scanner, an infrared image of a bar code associated with an item for sale;

determining, using a computer connected to the point-of-scale scanner, that the item for sale associated with the bar code is allowed for purchase by only a subset of customers;

configuring an ultraviolet filter mounted within the point-of-scale scanner to allow the passage of ultraviolet light within;

illuminating the identification card with ultraviolet light;

capturing, with the point-of-sale scanner, an image of the identification card that includes a fluorescent response to the ultraviolet light;

determining if the identification card is authentic by analyzing the captured image; and

determining, based at least in part on determining if the identification card is authentic, if the customer is a member of the subset of customers allowed to purchase the item for sale.

2. The method of claim 1, further comprising configuring the ultraviolet filter to block the passage of ultraviolet light within prior to capturing the infrared image.

3. The method of claim 1, wherein determining if the identification card is authentic comprises detecting the presence or absence of ultraviolet-luminescent material in the identification card.

4. The method of claim 1, further comprising capturing, with the point-of-sale scanner, a second image of the identification card when the identification card is not illuminated with ultraviolet light, wherein determining if the identification card is authentic further comprises analyzing the second image.

5. The method of claim 4, wherein determining if the identification card is authentic comprises determining differences between the image and the second image and comparing the differences to data in a memory.

6. The method of claim 1, wherein the item for sale comprises an alcohol product, a tobacco product, or a drug product.

7. The method of claim 1, wherein the step of determining if the identification card is authentic is performed on the point-of-scale scanner, at a point-of-sale computer, or on a remote server computer.

8. The method of claim 1, further comprising providing audio or haptic feedback upon determining that the identification card is authentic.

9. A point-of-sale scanner comprising:

a light source for providing infrared and ultraviolet light;

an image sensor for capturing image data;

a filter for filtering ultraviolet light;

a filter controller for configuring the filter such that, in a first mode, the filter blocks ultraviolet light from striking the sensor and, in a second mode, permits ultraviolet light to strike the sensor; and

a computer processor configured for controlling the light source, image sensor, and filter controller such that the point-of-sale scanner captures an image of a bar code associated with an item for sale while the light source illuminates the bar code with infrared light provided by the light source and while the filter filters ultraviolet light from the light source and, if the item for sale associated with the bar code is allowed for purchase by only a subset of customers, then the point-of-sale scanner captures an image of the identification card while the identification card is being illuminated by ultraviolet light provided by the light source and for transmitting image data captured by the image sensor to a remote computer for determining if the customer is a member of the subset of customers allowed to purchase the item for sale.

10. The system of claim 9, wherein the computer processor is further configured for controlling the light source, image sensor, and filter controller such that the point-of-sale scanner captures a second image of the identification card while the identification card is being illuminated by ambient light.

11. The system of claim 9, further comprising a point-of-scale computer in communication with the point-of-scale scanner.

12. The system of claim 10, further comprising a computer display in communication with the point-of-scale computer.

13. The system of claim 9, wherein the point-of-scale scanner further comprises a speaker for providing audio feedback.

14. The system of claim 9, wherein the point-of-scale scanner further comprises a vibrating element for providing haptic feedback.

15. The system of claim 9, wherein the point-of-scale scanner further comprises a computer memory for storing the image data.

16. The system of claim 9, wherein filter controller comprises a mechanism for moving the filter.

17. The system of claim 9, wherein filter controller comprises an electrical circuit for changing an electrical property of the filter.

18. The system of claim 9, wherein the light source comprises a first LED for providing infrared light and a second LED for providing ultraviolet light.

19. The system of claim 9, wherein the light source comprises an LED for providing both infrared and ultraviolet light.
