Daily Headlines – University of Arkansas: “Engineering researchers at the University of Arkansas have developed a unique and robust method to prevent cloning of passive radio frequency identification tags. The technology, based on one or more unique physical attributes of individual tags rather than information stored on them, will prevent the production of counterfeit tags and thus greatly enhance both security and privacy for government agencies, businesses and consumers.” – The researchers found that different tags responded to a range of radio frequencies from 903 to 927 MHz, giving them unique characteristics that could be reproduced for identification purposes; electronic fingerprinting. According to the article, this electronic fingerprinting increases security without increasing the cost of producing RFID tags.
Healthcare IT Consultant Blog: “VeriChip Corporation Outlines Current Applications and Potential Future Applications for its First-of-a-Kind Implantable RFID Implantable Microchip - VeriChip Corporation, a provider of radio frequency identification (RFID) systems for healthcare and patient-related needs, today provided additional comments regarding its VeriMed™ Health Link patient identification system following the recent passage of a bill by the Pennsylvania House of Representatives banning forced microchip implantation in humans, and also outlined its current and potential future applications for its RFID implantable microchip. The VeriMed Health Link system was cleared by the FDA in 2004 as a Class II medical device and is the first and only implantable microchip cleared by the FDA for patient identification. “

Barcode.com: “RFID, or radio frequency technology, uses a tag applied to a product in order to identify and track it via radio waves. The 2 parts that make up the tag are an integrated circuit and an antenna. While the circuit processes and stores information, the antenna transmits signals to the RFID reader, also called an interrogator, in order to interpret the data in the tag. In contrast, a barcode is an optical representation of data that can be scanned and then interpreted. The data is represented by the width and spacing of parallel lines, and are often used in POS applications, in addition to tracking objects throughout the supply chain.” – The article goes on to give the advantages of both technologies. The more I read about RFID technology, the more interested I become. While the technology hasn’t really caught fire in health care, I think the utility of RFID demands further investigation.
9to5mac.com: “RFID reader built into the screen? We’re not quite sure why they’d need to do this (as opposed to putting the reader somewhere else in the device) but Apple has put a patent application on this.” – In addition, the US Patent and Trademark Office lists the following: “The efficient incorporation of RFID circuitry within touch sensor panel circuitry is disclosed. The RFID antenna can be placed in the touch sensor panel, such that the touch sensor panel can now additionally function as an RFID transponder. No separate space-consuming RFID antenna is necessary. Loops (single or multiple) forming the loop antenna of the RFID circuit (for either reader or tag applications) can be formed from metal on the same layer as metal traces formed in the borders of a substrate. Forming loops from metal on the same layer as the metal traces are advantageous in that the loops can be formed during the same processing step as the metal traces, without requiring a separate metal layer.” - I can think of several uses for an iPhone with a built in RFID Tag reader, it can already read barcodes. The iPhone just keeps getting cooler and cooler.
TheHealthCareBlog.com: “When Harvard Medical School and CareGroup CIO Dr. John Halamka agreed to place his medical information on an RFID chip and have it implanted it in his arm, he triggered an instant global spotlight on this unusual form of portable electronic medical record. The decision, made in December 2004 and disclosed in early 2005, captured worldwide attention from places a diverse as Fox News, the BBC and the New England Journal of Medicine (where Halamka contributed a commentary ).
As recently as 2007, a debate over chip privacy and safety versus having critical medical data instantly at hand (as it were) was featured in a PLoS Medicine exchange. In it, Halamka asserted, “Implantation of RFID devices is one tool, appropriate for some patients based on their personal analysis of risks and benefits, that can empower patients by serving as a source of identity and a link to a personal health record when the patient cannot otherwise communicate.””
