Abstract
A method for validating a quick response code includes steps or acts of: receiving a captured enhanced quick response code that included a static component and a dynamic component; validating the quick response code in the static component using the auxiliary data in the dynamic component; and returning a token when the quick response code is validated.
Claims20
A method for validating a quick response code, said method comprising:
- using an input/output interface coupled to a processor device, performing:
- receiving a captured enhanced quick response code comprising a static component and a dynamic component;
- wherein the static component comprises a traditional quick response code;
- wherein the dynamic component is coupled with the static component and comprises auxiliary data used to validate the quick response code;
- validating the quick response code in the static component using the auxiliary data in the dynamic component;
- and
- returning a token when the quick response code is validated.

A method for validating a quick response code, comprising:
- using an input/output interface coupled to a processor device, performing:
- capturing an enhanced quick response code comprising a static component and a dynamic component;
- wherein the static component comprises a quick response code with a location identifier;
- wherein the dynamic component is coupled with the static component and comprises auxiliary data used to validate the quick response code;
- transmitting both components of the captured enhanced quick response code to a validation engine for validating the quick response code;
- and
- receiving a token from the validation engine when the quick response code is validated.
