Which Tags Work Better Near Metal And Fluids; Why Are Consumers Expected To See Cost Increases Passed To Them When The Key Purpose Of Rfid Is To Lower Costs; How Will European Supply Chain Centres Be Negatively Impacted By Regulations Imposed By Etsi - SATO CL408e Rfid Manual

identify products, cases, and other items to provide increased productivity and save on
labour costs compared to barcodes, virtually eliminating the need to have people locate
items and manually scan barcodes.
Q: Which tags work better near metal and fluids?
Tags with lower frequencies tend to read better near metals or fluids. This is due to radio
waves bouncing off of metal and or being easily absorbed by water in correlation to higher
frequencies.
Q: Why are consumers expected to see cost increases passed to them when the key
purpose of RFID is to lower costs?
Consumers may see cost increases passed to them during the initial stages of RFID tag
implementation. This is due to the necessary changes of the information systems
infrastructure, such as middleware, which is designed with support for RFID systems in
order to filter information to software applications. Another problem could happen if an item
has a defective RFID tag that could not be read. These items would require manual entry
at checkout, inventory time, receiving time, etc.
Q: How will European supply chain centres be negatively impacted by regulations
imposed by ETSI?
While global companies are moving rapidly to adopt RFID systems that can operate in the
UHF spectrum, regulations proposed by the European Telecommunications Standards
Institute (ETSI) won't enable European companies to use UHF systems for supply chain
management. ETSI currently allows only 0.5 watts of effective radiated power (ERP) in a
narrow 250 kHz band range from 869.4 to 869.65 MHz. This allocation is for short-range
devices which can only be on 10 percent of the time. The Federal Communications
Commission (FCC) of the United States is more lenient on U.S. companies, allowing them
to deploy RFID readers that emit 4 watts effective isotrophic radiated power in the
Version 0.8
Unfortunately, every technology has its limits. RF tags and
transponders transfer information by way of radio waves and are
subjected to interference—predominantly by metal and liquid
products, especially when merchandise is packaged in metal cans or
containers. These potential sources of interference must be
recognised and accounted for during system planning.
