 "Gentag Allows Cell Phones To Become RFID Readers")
Gentag, recently announced the issuance of Patent 7148803 entitled “Radio Frequency Identification (RFID) Based Sensor Networks.”
This patent covers the use of personal wireless devices such as cell phones, PDAs, and laptops as low-cost wireless readers for RFID sensors and the creation of RFID-sensor networks for consumer, industrial, and government applications.
This patent provides the basis for the creation of the next generation wireless technology, combining low-cost wireless readers in the hands of the consumers, wireless networks, geolocation, and disposable wireless sensors for various market applications.
The emergence of Near Field Communications (NFC) will accelerate the availability of RFID cell phones, thereby accentuating the importance of the patent.
Low-cost disposable RFID sensors are now possible with Gentag’s single - point-calibration temperature-reference circuit. RFID-reader-enabled cell phones are either already available or under development with major cell phone manufacturers worldwide for both the 13.56 and UHF (Gen-2) frequencies.
By combining RFID cell phones and RFID sensors with cellular networks or the Internet, the consumer will be empowered to read any RFID sensor tag anywhere for almost any application.
For example, consider using an RFID cell phone to read the storage history of a wine bottle prior to purchase, to ensure that a drug interaction is unlikely to occur for an individual prior to taking a given medication, or to remotely monitor or control an
RFID networked device in a home using a cell phone or a laptop.
A particular focus area for Gentag is to combine RFID cell phones with RFID sensors for specialized diagnostic applications such as integrating RFID sensors into low-cost disposable diagnostic devices such as “smart” disposable wireless skin patches or personal drug- delivery systems and read directly with a cell phone.
Patent 7148803 is co-owned between Altivera, a Gentag operated company, and Symbol Technologies (Motorola).
