Metal card with biometric features

A method for making a transaction card, the method comprising the steps of:

• (a) providing at least one metal layer;
• (b) providing at least one inlay layer comprising a biometric sensor, one or more payment interface components configured to interface with a card reader;
• a secure element configured to exchange information with the card reader pursuant to processing a financial transaction;
• at least one logic component connected to the biometric sensor and configured to compare information detected by the biometric sensor to stored information and to enable processing of the financial transaction only upon a detected match between the detected and stored information;
• and
• visible indicia on a front outer surface of the card aligned with the biometric sensor to signify a lateral location of the sensor relative to a periphery of the card, such that the biometric sensor is not visible from the front outer surface of the card;
• (c) assembling the card with the biometric sensor and the one or more payment interface components in communication with the inlay and configured to obtain transaction information and biometric information originating from a location on or above the metal layer;
• and
• wherein at least a portion of the at least one metal layer or a further layer overlies the biometric sensor.

A method for making a transaction card, the method comprising the steps of:

• (a) providing at least one metal layer;
• (b) creating a plurality of openings in the metal layer, and a plurality of grooves in the metal layer connecting respective openings;
• (c) inserting in respective openings of the plurality of openings each of a plurality of electronic components, the plurality of electronic components comprising:
• a biometric sensor configured to obtain biometric information originating from a location on or above the metal layer, such that the biometric sensor is not visible from a front outer surface of the transaction card,
• one or more payment interface components configured to interface with a card reader and configured to obtain transaction information originating from a location on or above the metal layer,
• a secure element configured to exchange information with the card reader pursuant to processing a financial transaction, and
• at least one logic component configured to communicate with the biometric sensor and to compare information detected by the biometric sensor to stored information and to enable processing of the financial transaction only upon a detected match between the detected and stored information;
• (d) creating electrical connections among predetermined inputs and outputs of the electronic components, the electrical connections comprising metallic traces disposed in the plurality of grooves;
• (e) providing visible indicia on the front outer surface of the card, the visible indicia being aligned with the biometric sensor to signify a lateral location of the sensor relative to a periphery of the card;
• and
• wherein at least a portion of the at least one metal layer or a further layer overlies the biometric sensor.

A metal transaction card comprising:

• at least one metal layer;
• a biometric sensor;
• one or more payment interface components configured to interface with a card reader;
• a secure element configured to exchange information with the card reader pursuant to processing a financial transaction;
• at least one logic component connected to the biometric sensor and configured to compare information detected by the biometric sensor to stored information and to enable processing of the financial transaction only upon a detected match between the detected and stored information;
• visible indicia on a front outer surface of the card aligned with the biometric sensor to signify a lateral location of the sensor relative to a periphery of the card, such that the biometric sensor is not visible from the front outer surface of the card;
• and
• wherein at least a portion of the at least one metal layer or a further layer overlies the biometric sensor,
• wherein one or more the biometric sensor, the one or more payment interface components, the secure element, and the at least one logic component are disposed on an inlay,
• wherein the inlay has lateral dimensions smaller than lateral dimensions of the card,
• wherein the inlay comprises a first inlay layer coextensive with the card and a second inlay layer received in a pocket formed in the at least one metal layer and surrounded by an encapsulant.
