24 Guidel<strong>in</strong>ePJM StackTag Ò , Magellan <strong>Technology</strong> Pty Ltd, Sydney, Australia1. Is an <strong>RFID</strong> tag that can be operated <strong>in</strong> stacks <strong>of</strong> many hundred <strong>RFID</strong> tags without separation2. Is unique and does not depend on tuned <strong>RFID</strong> tags to operate3. Chips and <strong>in</strong>lets use a unique method to operate on low field strength4. Inlets are not designed <strong>for</strong> resonance frequency (most tags have a self-resonance frequency between 14 and 70 MHz)5. StackTag <strong>in</strong>lets do not detune by o<strong>the</strong>r <strong>RFID</strong> tags or materials and will operate even on metal or under water6. Inlets are designed ei<strong>the</strong>r <strong>for</strong> range or <strong>for</strong> maximum stackability7. Inlet design is easy and as tags are robust to any detun<strong>in</strong>g exist<strong>in</strong>g <strong>in</strong>let <strong>for</strong>m factors can be used <strong>for</strong> easy pilot project<strong>in</strong>stallationPortal – A door or o<strong>the</strong>r po<strong>in</strong>t <strong>in</strong> a facility surrounded by fixed <strong>RFID</strong> readers to identify and track <strong>the</strong> flow <strong>of</strong> product. Load<strong>in</strong>gdock doors are a typical example.Reader – Also known as an <strong>in</strong>terrogator. Typically a network-based device and antenna configuration, which reads <strong>the</strong><strong>in</strong><strong>for</strong>mation conta<strong>in</strong>ed on an <strong>RFID</strong> tag. In passive operations, <strong>the</strong> reader supplies <strong>the</strong> tag with power. Readers can be fixedposition <strong>for</strong> load<strong>in</strong>g dock door or o<strong>the</strong>r portal applications, or embedded <strong>in</strong>to mobile devices <strong>for</strong> <strong>in</strong> store or exception report<strong>in</strong>grequirements.Rollout – When pilots provide sufficient evidence <strong>of</strong> a strong return on <strong>in</strong>vestment, companies are expected to deploy (rollout)<strong>the</strong> technology <strong>in</strong>to greater parts <strong>of</strong> <strong>the</strong>ir supply cha<strong>in</strong>. This process is expected to result <strong>in</strong> significant growth <strong>for</strong> <strong>the</strong><strong>RFID</strong> <strong>in</strong>dustry.Smart Storage – In this context <strong>the</strong> authors mean smart solutions <strong>in</strong> storages, which allow <strong>the</strong> quick and easy f<strong>in</strong>d<strong>in</strong>g <strong>of</strong> adef<strong>in</strong>ite unit <strong>in</strong> storage rooms or cab<strong>in</strong>ets.Tag – Also referred to as transponder or transponder tag, which is typically affixed to an item <strong>for</strong> track<strong>in</strong>g purposes. Composed<strong>of</strong> a semi-conductor chip and antenna held toge<strong>the</strong>r <strong>in</strong> a substrate. Each tag has a manufacturer <strong>in</strong>stalled unique identificationnumber as well as additional few bits to many kilobits <strong>of</strong> <strong>in</strong>cremental memory. Passive tags receive energy from<strong>the</strong> reader, while active tags have an <strong>in</strong>ternal power supply.Track and Trace - Involves controll<strong>in</strong>g <strong>the</strong> shipp<strong>in</strong>g and receiv<strong>in</strong>g process <strong>for</strong> medical devices, as well as manag<strong>in</strong>g assetsand <strong>in</strong>ventories with<strong>in</strong> healthcare facilities.UID – Unique Identification is a US DoD-based number<strong>in</strong>g scheme to identify a broad range <strong>of</strong> high-value assets.UHF (Ultra High Frequency) <strong>RFID</strong> – <strong>RFID</strong> products that use <strong>the</strong> 868–950 MHz frequency band, which is regulated by governments.This frequency allows read ranges <strong>of</strong> 8–30 feet (2–4 times that <strong>of</strong> HF), but can be heavily affected by environmentalfactors, <strong>in</strong>clud<strong>in</strong>g liquids and metals, mandated by Wal-Mart and <strong>the</strong> US DoD <strong>for</strong> supply cha<strong>in</strong> applications.Write Once Read Many (WORM) – <strong>Use</strong>d to describe an <strong>RFID</strong> tag that allows only one set <strong>of</strong> data to be written on to it. It istypically used <strong>in</strong> applications where security is a concern.Ó 2010 The Author(s)Journal compilation Ó 2010 International Society <strong>of</strong> Blood <strong>Transfusion</strong>, Vox Sangu<strong>in</strong>is (2010) 98 (Suppl. 2), 1–24
