Abstract
Devices and methods for signature authentication of a bearer of a payment processing device during financial transactions are provided. The payment processing device is provided with a signature input panel configured to receive user input signature information for the purpose of authenticating the signature. After the bearer of the payment processing device writes her signature into the signature input panel, the input signature information is compared to a pre-stored signature profile stored in the payment processing device for authentication.
Claims19
A payment device comprising:
- a communication element;
- a signature input panel having a plurality of sensing layers for capturing input signature information including changes in pressure exerted on the signature input panel, the changes in pressure being captured by monitoring a number of activated pixel points between successive pair of the sensing layers when receiving an input signature;
- and
- a processor configured to compare the input signature information against pre-stored signature information, and to activate the communication element when the input signature information matches the pre-stored signature information.

A signature verification device, comprising:
- a signature input panel configured to receive input signature information from a user, the signature input panel comprising a plurality of sensing layers and configured to measure changes in pressure when pressure is exerted on the signature input panel by monitoring a number of activated pixel points between successive pair of the sensing layers;
- a processor, coupled to the signature input panel, configured for comparing the input signature information against a reference signature profile;
- and
- an output component coupled to the processor for outputting an indication representing a result of the comparison of the input signature information against the reference signature profile.
