Database Query Methods and Systems Using Machine-Readable Optical Codes

Abstract

Systems and methods for database querying using machine-readable optical codes are provided. A system receives machine-readable optical code information associated with a listing entity from a user device, determines the listing entity based on the received optical code information, and retrieves one or more property listings associated with the listing entity from a database. The system receives geolocation data of the user device and filters the property listings based on the geolocation data to determine a first property listing having a closest proximity to the user device. The system transmits the first property listing to the user device for display. A method for database querying involves determining a listing entity based on computer-readable optical code information that is associated with the listing entity and received from a user device. One or more property listings are retrieved from a database and filtered based on received geolocation data of the user device.

Dependencies are inferred from the claim text.
