Security authentication using payment card display devices at accepted merchant locations

A method comprising:

• in response to a wireless beacon at a merchant location detecting a payment card in a first proximity range to the wireless beacon using short range communication signals, determining the merchant location;
• receiving, via a network interface component, payment card data for the payment card from the wireless beacon;
• accessing, by account module comprising at least one hardware processor, accepted payment sources for a merchant device associated with the merchant location;
• determining a match between the payment card and the accepted payment sources using the payment card data;
• in response to the match, activating, using the wireless beacon, a visual output component of the payment card in possession of a user at the merchant location using the short range communication signals of the wireless beacon, wherein the visual output component comprises at least an light emitting diode (LED), and wherein the activating the visual output component comprises causing the LED to turn on;
• generating a security code specific to the payment card and the merchant device, wherein the security code is required to be matched between the payment card and the merchant device for transaction processing using the payment card at the merchant location;
• and
• communicating the security code to the payment card and the merchant device, wherein matching the security code between the payment card and the merchant device by the merchant device authenticates use of the payment card with the merchant device for the transaction processing when scanning the payment card by the merchant device.

A non-transitory machine-readable medium having stored thereon machine-readable instructions executable to cause a machine to perform operations comprising:

• in response to a wireless beacon at a merchant location detecting a payment card in a first proximity range to the wireless beacon using short range communication signals, determining the merchant location;
• receiving, via a network interface component, a payment card data from a wireless beacon;
• accessing, by account module comprising at least one hardware processor, accepted payment sources for a merchant device associated with the merchant location;
• determining a match between the payment card and the accepted payment sources using the payment card data;
• in response to the match, activating, using the wireless beacon, a visual output component of the payment card in possession of a user at the merchant location using the short range communication signals of the wireless beacon, wherein the visual output component comprises at least an light emitting diode (LED), and wherein the activating the visual output component comprises causing the LED to turn on;
• generating a security code specific to the payment card and the merchant device, wherein the security code is required to be matched between the payment card and the merchant device for transaction processing using the payment card at the merchant location;
• and
• communicating the security code to the payment card and the merchant, wherein matching the security code between the payment card and the merchant device by the merchant device authenticates use of the payment card with the merchant device for the transaction processing when scanning the payment card by the merchant device.
