Abstract
An authentication reader and a dispenser comprising the authentication reader for authenticating a product having a taggant ink disposed on the product's surface.
Claims20
An authentication reader for authenticating a product having a taggant ink disposed upon a surface of the product, the reader comprising:
- a signal generator comprising an excitation source that provides a light source having a source wavelength or wavelengths producing a signal response from a taggant ink, wherein the signal response comprises a spectrum of intensity peaks at multiple wavelengths and the multiple wavelengths are different from the source wavelength;
- a sensor for receiving the signal response from the taggant ink;
- a filter, positioned between the signal generator and the sensor, for blocking the source wavelength or wavelengths from the sensor;
- and
- control circuitry coupled to the signal generator, the sensor and a database containing data corresponding to signal responses associated with taggant ink, wherein the control circuitry compares the signal response with the data of an expected signal response stored in the database to determine if the signal response matches an expected signal response in the database, and positively authenticate the product as authentic when the signal response matches the data.

A dispenser having the ability to authenticate a beverage containing cup comprising:
- a base unit for retaining a beverage containing cup having a taggant ink disposed upon a surface of the cup;
- an authentication reader for authenticating a beverage containing cup comprising:
- (1) a signal generator comprising an excitation source that provides a light source having a source wavelength or wavelengths producing a signal response from a taggant ink, wherein the signal response comprises a spectrum of intensity peaks at multiple wavelengths and the multiple wavelengths are different from the source wavelength;
- (2) a sensor for receiving the signal response from the taggant ink;
- (3) a filter, positioned between the signal generator and the sensor, for blocking the source wavelength or wavelengths from the sensor;
- and
- (4) control circuitry coupled to the signal generator, the sensor and a database containing data corresponding to signal responses associated with taggant ink, wherein the control circuitry compares the signal response with the data of an expected signal response stored in the database to determine if the signal response matches an expected signal response in the database, and positively authenticate the beverage containing cup as authentic when the signal response matches the data;
- and
- a dispensing mechanism for dispensing a beverage via the beverage dispensing cup upon the beverage dispensing cup being authenticated.
