Abstract: In some examples, a system may receive, from a merchant device, an indication of a transaction between a merchant and a customer, including transaction information associated with the transaction. The system may further receive, from the merchant device, a signal from a customer device associated with the customer and received by the merchant device. Based on the transaction information, the system may determine a previous signal previously received from the customer device, and at least one previous parameter associated with the previous signal. The system determines at least one parameter associated with the received signal and determines a presence indication based on comparing the previous parameter and the determined parameter. For example, the presence indication may be indicative of the customer device being physically present at or near a geographical location of the merchant device. Based on the presence indication, the system may send an instruction to process the transaction.

Abstract: Introduced here is a technology that enables fraud detection and protection in financial transactions using a communication signal identification mechanism. The technology eliminates the uncertainties as to the authenticity of a payment card and/or a customer involved in a transaction. In at least some embodiments, methods and systems are disclosed for facilitating communication with one or more personal computing devices physically present at a merchant's POS device to establish customer presence and/or card presence. The personal computing devices can include a smartphone, a wearable electronic device, or any electronic device capable of communication with other devices. The personal computing devices can also include a payment card in the form of a smartcard with embedded BLE or any other smart chip (e.g., GPS, Wi-Fi, 4G, etc.). In some embodiments, methods and systems are disclosed for applying context-based restrictions on the payment card to assist in protection against fraud.

Abstract: Introduced here is a technology that enables fraud detection and protection in financial transactions using a communication signal identification mechanism. The technology eliminates the uncertainties as to the authenticity of a payment card and/or a customer involved in a financial transaction, such as a payment transaction. In at least some embodiments, methods and systems are disclosed for facilitating establishment of a card presence through communication with a payment card being used in a transaction instantiated on a merchant's POS device. The payment card can be in the form of a smartcard with embedded BLE or any other smart chip (e.g., GPS, Wi-Fi, 4G, LTE, etc.) capable of transmitting a communication signal that contains identifying information, which can be used to establish the card presence.
