System and method for guiding card positioning using phone sensors

Abstract

A position alignment system facilitates positioning of a contactless card in a sweet spot in a target volume relative to a contactless card reading device. Alignment logic uses information captured from available imaging devices such as infrared proximity detectors, cameras, infrared sensors, dot projectors, and the like to guide the card to a target location. The captured image information is processed to identify a card position, trajectory and predicted location using one or both of a machine learning model and / or a Simultaneous Localization and Mapping logic. Trajectory adjustment and prompt identification may be intelligently controlled and customized using machine-learning techniques to customize guidance based on the preference and / or historical behavior of the user. As a result, the speed and accuracy of contactless card alignment is improved and received NFC signal strength is maximized, thereby reducing the occurrence of dropped transactions.

[0001] Cross References to Related Applications [0002] This application claims priority to U.S. Patent Application Serial No. 16 / 511,683, filed July 15, 2019, entitled "SYSTEM AND METHOD FOR GUIDINGCARD POSITIONING USING PHONE SENSORS." The content of the aforementioned application is hereby incorporated by reference in its entirety. Background technique [0003] Near-field communication (NFC) includes a set of communication protocols that enable electronic devices, such as mobile devices and contactless cards, to communicate information wirelessly. NFC devices can be used in contactless payment systems, similar to those used by contactless credit cards and e-ticket smart cards. For example, NFC-enabled devices can act as electronic identity documents and key cards in addition to payment systems. [0004] For example, contactless devices (e.g., cards, tags, transaction cards, etc.) may use NFC technology based on, for example, radio frequency identification (RFID) standard...

Problems solved by technology

[0005] While the advantages of using the NFC communication channel for contactless card transactions are many, including simple setup and lower complexity, one difficulty facing NFC data exchange may be between devices with small antennas, including contactless cards. Difficulty transmitting signals between

During an NFC exchange, movement of the contactless card relative to the device may undesirably affect the received NFC signal strength at the device and interrupt the exchange

Additionally, the characteristics of the card (e.g. metal) may cause noise, inhibit signal reception, or other reflections that falsely trigger NFC read transactions

For systems that use contactless cards for authentication and transaction purposes, delays and disruptions can lead to lost transactions and customer dissatisfaction
