Automatic Identification Technology for identifying items Three step process 1) Identify people/objects 2) Obtains information 3) Transfers data to computer
Radio Frequency Identification Auto ID with a wireless system Via radio waves No physical contact with product
3 Parts to the RFID System Antenna Transceiver with a decoder Tag or transponder
How the System Works Antenna sends out radio signal Reader sends out electromagnetic waves Tag passes through electromagnetic zone Tag transmits data to reader Reader decodes data from tag Data gets passed into a computer
Tags: Active vs Passive ActivePassive Powered by an internal batteryObtain power generated from the reader Data can be modified/rewritten onto the tag Tags are read-only and cannot be modified Greater sizeMuch lighter than active tags More expensiveLess expensive Limited operational lifeUnlimited operational life Longer read rangeShorter read range
Components of the System Tags- Shapes and Sizes Antennas- Shapes and Sizes Frequency Ranges Cost, security, speed and distance
Applications- RFID Technology Currency/Euro Patients and personnel Consumer packaged goods Apparel Highway toll tags Car keys
Applications for Businesses Inventory Control - movement and tracking of goods through supply chain Process of Manufacturing Goods Consumers - easy payment and automatic warranty registration Retailers - gain customer info, better marketing.
Benefits for Businesses Technology does work the employees don’t have to Benefits- Reduces admin error, labor costs and internal theft
Advantages vs Disadvantages ADVANTAGES Distance and movement Substances Memory DISADVANTAGES Expensive Metals Security Consumer products
