Currency validation

1. A method, comprising:

directing a controller board of a currency validation device to selectively illuminate a currency bill placed in front of a field-of-view of a camera by a cashier at a Point-Of-Sale (POS) terminal during a transaction at the POS terminal by using two selected light sources from a plurality of different types of available light sources, wherein the camera is integrated into a scanner of the POS terminal, wherein directing is responsive to the cashier instructing the controller board to perform illumination on the currency bill using the two selected light sources selected from:

Ultraviolet (UV), Infrared (IR) light, and white light;

instructing the camera to take an image of the illuminated currency bill; and

presenting the image in a screen of a display for validation, wherein presenting further includes visually depicting at least one security feature of the currency bill in the image on the display when the currency bill is legitimate where the at least one security feature includes one whited out vertical line and one dark vertical line that were not visible when viewing the currency bill as opposed to the image of the currency bill;

programming a microcontroller of the controller board through a device port of the controller board using a programming interface;

interacting with the camera via a camera interface of the controller board; and

processing the method as a currency validation system at the POS terminal during the transaction through interaction between the POS terminal, the camera, and the controller board.

2. The method of claim 1 , wherein directing further includes obtaining selections for the two selected light sources from the cashier as a cashier initiated instruction.

3. The method of claim 1 , wherein directing further includes sending, by the scanner, an instruction to the controller board to illuminate the currency bill.

4. The method of claim 1 , wherein directing further includes sending, by, the POS terminal, an instruction to the controller board to illuminate the currency bill.

5. The method of claim 1 , wherein directing further includes sending, by one of:

a laptop, a personal computer, a tablet, and a wearable processing device, an instruction to the controller board to illuminate the currency bill.

6. The method of claim 1 , wherein presenting further includes presenting the image in the screen of the display, wherein the display is a checkout station operated by the cashier and the cashier inspects the image for validation on the screen during the transaction with a customer, wherein the customer presented the currency to the cashier for payment of the transaction.

7. The method of claim 1 further comprising, sending the image to an image processor for validating the currency based on the two selected light sources that illuminated the currency, a denomination for the currency, and a government associated with issuing the currency.

8. A system, comprising:

a Point-Of-Sale (POS) device;

a scanner having an integrated camera interfaced to the POS device; and

a controller board of a currency validation device adapted and configured to:

i) selectively activate different types of light sources to illuminate currency placed in front of a field-of-view of the camera by a cashier during a transaction at the POS device based on instructions received that identify the different types of light sources received from the cashier operating the POS device, the cashier selecting two of the different types of light sources from: Ultraviolet (UV) light, Infrared (IR) light, and white light;

wherein the camera is adapted and configured to image the illuminated currency, and the POS device is adapted and configured to present the image within a screen of a display associated with the POS device for currency validation, and wherein at least one security feature of the currency is depicted in the image on the display as one whited out vertical line and one dark vertical line when the currency is legitimate where the at least one security feature was not visible when viewing the currency as opposed to the image of the currency;

wherein the controller board including a port configured to:

receive the instructions and program a microcontroller of the controller board through a programming interface;

wherein the system is a currency validation system configured to perform currency validation during the transaction through interactions between the POS device, the scanner, and the controller board;

wherein the controller board includes a camera interface for directly interacting with the camera.

9. The system of claim 8 , wherein the POS device is adapted and configured to control operation of the controller board.

10. The system of claim 8 , wherein the scanner is adapted and configured to control operation of the controller board.

11. The system of claim 8 further comprising, an image processor configured and adapted to:

i) recognize attributes in the image based on a type of light source that illuminated the currency when the image was taken and ii) compare the attributes against predefined attributes to automatically determine whether the currency is valid or a counterfeit.

12. The system of claim 11 , wherein the image processor is integrated into the POS device.

13. The system of claim 11 , wherein the image processor is remotely located over a network from the POS device.
