Patent attributes
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.
