Medical/Healthcare

• Patient monitoring and tracking – Patient location in hospital– Patient would have tag installed – typically

UHF or Active • Patient verification

– Scan wristband-type device (HF) • Staff tracking in hospital.

– UHF or Active– Example in accident/emergency department

In Hospitals Geo-fencing - Tracking Patients (research - WINMEC RFID Lab)

Research issues-Create zone filtration at each reader-Multiple readers help pin-point tag-Tracks location and movement of tag-Directional readers allow determination of floor-level-Investigating SAW technology for room delineation

4


Medical/Healthcare-Drug Authentication • Background

– Lawsuit against Amgen for counterfeit Epogen sold at CVS– Pfizer receives 4 complaints of potentially counterfeit Viagra in CA– In US, less than 1% of the drugs are counterfeit– Increasing counterfeiting overseas

• Solution– RFID tagging of drug bottles in factory– Track where the bottles have been in the supply chain– Verify bottle at pharmacy– Ensure that bottles have not been tampered with

• Technology– Short range RFID

• FDA report, February 2004, http://www.fda.gov/oc/initiatives/counterfeit/report02_04.html

WinRFID in Pharma

• RFID should provide minimum disruption to existing business process• …But there is a paradox…

• What is the business problem?

• Getting the authentic drug to the right place at the right time and delivered by the right person to the right person (chain of custody)

6


Medical/Healthcare – reduce human errors

• Reducing human errors

– Human error – In surgery, sponge getting left inside human body after procedure

– Approach – RFID tagging of sponges and scanning for sponges after surgery

– Organization – Stanford University – Issue – Reliability of read, Approval from

organizations such as FDA

Mobile Payments, Access and NFC

• Intro

• Requirements are similar – near field and security

• Card form factor

• Small, without battery

9


Toll Payment

• Efficiency in toll collection

• Toll is collected while car (object) is in motion, thereby eliminating the need for a human being to take the toll and for the driver to stop

• E.g. http://www.ezpass.com/ active

• E.g. http://www.wordiq.com/definition/FasTrak active

Examples of RFID-based payment systems

• Mobile-phone based RFID payments, chip in phone has pre-paid funds available http://www.rfidjournal.com/article/articleview/1197/1/1/

• NTT DoCoMo smart-card handsets with i-mode Felica® mobile wallet service

• Payment of drinks by VIP customers (tags embedded in skin) http://www.adsx.com/investorrelations/pdfs/VeriBro.pdf

• Exxon Mobil RFID Speedpass

11


Payment in Mass Transit System

• Bay area mass transit system

– TransLink cards by ASK• 8 KB of memory• Passive• ISO 14443B• 13.56 Mhz

– Readers installed on trains and buses

Near Field Communications

• Established by Nokia, Philips and Sony

• Touch/proximity based action

• NFC technology evolved from a combination of contact-less identification (RFID) and interconnection technologies

• 13.56 MHz (HF)

• Distance is a few centimeters

13


Near Field Communications• NFC technology is standardized in ISO

(International Standards Organization) 18092, ECMA 340, and ETSI (European Telecommunications Standards Institute) TS 102 190.

• Compatible to the broadly established contact-less smart card infrastructure based on ISO 14443 A (Philips MIFARE(R) technology & Sony's FeliCa* card)

• NFC forum
