Abstract

Disclosed is method for utilizing a Radio Frequency Identification (RFID) reader to communicate with a server from a mobile device. The method provides additional context-aware filtering and analytics of the RFID data by combining the dynamic contextual information from the smartphone with the static information encoded on, and read from, the RFID tag.

A Method and System for Mobile Phone Enabled Context-Aware RFID Data Management

Existing systems use Radio Frequency Identification (RFID) tags to store information about an individual person and make that information available to any device that can read the tag. As an example, conference badges and some business cards contain embedded RFID tags that store information about the carrier/owner. However, this information is completely static and there is no indication of the context in which the system reading the RFID tag exists.

Existing systems employ a fixed position RFID reader to detect and read an RFID tag and combine the tag's data with static information maintained by the fixed reader. Several products allow smartphones to act as RFID readers. However, smartphones can also gather rich dynamic context about the current environment (e.g., the geo-location of the phone, the date and time, and the identity of the person operating the phone). This dynamic context can change every time an RFID tag is read, even if the tag is the same.

A method is needed to enhance the functionality of an RFID reader by including

dynamic information.

The novel solution in a method to provide additional context-aware filtering and analytics of the RFID data by combining the dynamic contextual information from the smartphone with the static information encoded on, and read from, the RFID tag.

This system leverages the dynamic context gathering capabilities of the smartphone to influence the processing of personal identification data that is encoded in RFID tags. The contextual data is used to classify the user's/owner's RFID data, further organize, and manage a broader scope of information about that person than that which was stored in the RFID tag. The context in which the RFID tag data is obtained allows greater intelligence to be applied when managing the tag owner's information.

The basic idea is to use RFID data read via a mobile device as an index into a database entry containing additional information. A mobile application reads the RFID

data and collects contextual information such as current location and time. The contextual information along with the RFID data is sent to a remote server to determine

which fields in the database should be sent back to the mobile application. The mobile application receives the data from the server and renders it on the display.

The mobile application also provides a user interface to manage the data that is associated with the RFID tag. The owner of the RFID tag specifies what professional information should be available for sharing via his RFID tag. For example, the owner enters references to associated online profiles (e.g., professional or social networks, services, etc.). The owner can also enter data pertaining to different categories such as medical, customer loyalty programs, etc.
