Abstract

In some examples, methods and systems may process one or more payment transactions between a merchant and a customer by registering, by a biometric sensor of a payment object reader or a mobile device, a biometric characteristic as a biometric payment instrument, for example by obtaining data corresponding to a biometric characteristic of the customer. The data is converted into a digital signature of the biometric characteristic and compared with a registered biometric instrument at the time of transaction. If a match is obtained, the customer effects payments through the registered biometric instrument.

First claim

What is claimed is:

1. A method for processing a payment transaction between a merchant and a customer, the method comprising:
obtaining, by a biometric sensor associated with a point-of-sale (POS) terminal, a biometric characteristic of the customer;
generating, by a signature component of the biometric sensor, a digital signature of the biometric characteristic;
generating, by the POS terminal, a payment request including the digital signature and a money transfer amount corresponding to the payment transaction;
detecting, by a sensor associated with the POS terminal, a proximate computing device associated with the customer in proximity to a current geographical location of the POS terminal based at least in part on an identifier associated with the proximate computing device;
establishing, by the POS terminal, a communication link with the proximate computing device;
sending, by the POS terminal, the payment request to the proximate computing device communicatively coupled to the POS terminal;
determining, by a comparator of the proximate computing device, a match between the digital signature and a registered biometric instrument stored in a database;
determining, by the proximate computing device and from the registered biometric instrument, an identity of the customer associated with the registered biometric instrument in response to determining the match;
identifying, by the proximate computing device, a customer financial account associated with the identified customer, based on a stored association between the customer financial account and the identified customer; and
generating, by the proximate computing device, a payment transfer request based on the customer financial account, the payment transfer request including the money transfer amount; and
sending, by the proximate computing device, the payment transfer request to a payment processing system.

2. The method of claim 1 , wherein the biometric characteristic is selected from a group of characteristics including a thumbprint, a fingerprint, a retinal iris scan, a speech pattern, a voice print, a facial geometry, a facial image, and a genetic signature.

3. The method of claim 1 further comprising accessing a database associated with the proximate computing device, wherein the database includes a plurality of biometric instruments registered by the customer, wherein each of the biometric instruments corresponds to a tokenized representation of a unique biometric characteristic of the customer.

4. The method of claim 1 further comprising:
causing display of information regarding the payment transaction on the proximate computing device associated with the customer, wherein the information includes one of a request for authorization of the payment transaction or details of the payment transaction,
wherein the biometric characteristic of the customer is received as a payment object for the payment transaction.

5. The method of claim 1 , wherein identifying the financial account further comprises:
evaluating, by the payment processing system, whether the payment transaction complies with stored condition data, wherein the stored condition data includes at least one of: a time period within which the money transfer amount is accessible to the merchant; a particular merchant requesting the money transfer amount; a particular category of the merchant requesting the money transfer amount;
a particular location from where the customer is requesting the money transfer amount; a predefined limit of the money transfer amount; the identity of the customer making the purchase; and a particular type of goods or services corresponding to the money transfer amount;
deciding to authorize payment for the transaction and to fund the payment transaction from the customer financial account if said evaluating results in a determination that the payment transaction complies with the stored condition data, and otherwise, deciding to deny the payment transaction; and
transmitting an electronic message indicative of an outcome of the evaluation, from the payment processing system to the POS terminal.

6. The method of claim 1 , wherein a registration of the biometric instrument includes the user associating a condition with the biometric instrument, the condition comprising at least one of:
a time period within which the money transfer amount is accessible to the merchant;
a particular merchant requesting the money transfer amount;
a particular category of the merchant requesting the money transfer amount;
a particular location from where the customer is requesting the money transfer amount;
a predefined limit of the money transfer amount;
the identity of the user making the purchase; or
a particular type of goods or services corresponding to the money transfer amount.

7. The method of claim 1 , wherein detecting the proximate computing device further comprises:
activating a geo-fence around the current geographical location of the POS terminal; and
determining that the proximate computing device has entered the geo-fence.

8. The method of claim 1 , further comprising:
storing the digital signature in the POS terminal; and
accessing the digital signature to validate a subsequent payment transaction between the merchant and the customer.

9. The method of claim 1 , further comprising deleting the biometric characteristic from the POS terminal when the digital signature is generated.

10. The method of claim 1 , wherein the biometric characteristic of the customer is received as a payment object for the payment transaction.

11. A system comprising:
a point-of-sale (POS) terminal comprising:
a biometric sensor;
one or more POS terminal processors; and
one or more POS terminal non-transitory computer-readable media storing instructions when executed by the one or more POS terminal processors causes the one or more POS terminal processors to perform acts comprising:
obtaining, by the biometric sensor, a biometric characteristic of the customer;
generating, by a signature component of the biometric sensor, a digital signature of the biometric characteristic;
generating a payment request including the digital signature and a money transfer amount corresponding to the payment transaction;
detecting a proximate computing device associated with the customer in proximity to a current geographical location of the POS terminal based at least in part on an identifier associated with the proximate computing device;
establishing a communication link with the proximate computing device;
sending the payment request to the proximate computing device communicatively coupled to the POS terminal; and

the proximate computing device comprising:
one or more proximate computing device processors; and
one or more proximate computing device non-transitory computer-readable media storing instructions when executed by the one or more proximate computing device processors cause the one or more proximate computing device processors to perform acts comprising:
receiving the payment request from the POS terminal;
determining a match between the digital signature a registered biometric instrument stored in a database;
determining, from the registered biometric instrument, an identity of the customer associated with the registered biometric instrument in response to determining the match;
identifying a customer financial account associated with the identified customer, based on a stored association between the customer financial account and the identified customer;
generating a payment transfer request based on the customer financial account, the payment transfer request including the money transfer amount; and
sending the payment
