What Are The Differences Between Barcodes And Rfid; Why Are Line-Of-Sight Barcode Readers At A Disadvantage Over Rfid Readers; Would Rfid Technology Ever Replace The Ever-Present Barcode; What Are Some Of The Typical Applications For Inductive Coupling Tags - SATO CL408e Rfid Manual

RFID readers are capable of automatically recognising and distinguishing all the RF tags
within their reading field. This capability allows the RFID reader to simultaneously process
all the data and provide for efficient material handling, packaging, and sorting of inventory.
Not only will these RFID readers be able to track tagged items and equipment, but they
can also be used to track patients (i.e. in hospitals).
D IFFERENCES BETWEEN RFID AND BARCODES
RFID and barcode are both identification technologies that allo
identification data to be stored and read back with a reader. While
barcodes have been around for ages, the idea of
using RFID in applications such as supply chain
management is a new concept. Hence, RFID has
been coined as the "wireless" or "radio" barcode.
Q : What are the differences between barcodes
RFID?
In contrast to barcode te
optical reader to read data, RFID reads data
using radio technology. The concept of RFID
driven by its greater data capacity that enables it
carry more information than barcodes. RFID
technology also enables tag reading from a
greater distance, even in harsh environments
unlike optical barcode readers, has no line-in-
sight requiremen t s in order to send and receive information.
Q

: Why are line-of-sight barcode readers at a disadvantage over RFID readers?

Line-of-sight between the label and a barcode reader is often difficult, unfeasible, or ev
impossible to achieve in industrial environments due to conditions such as dust or label
fading. By transferring data via radio waves, RFID has an advantage over barcodes in th
RFID tagged objects could be read through packaging, whether or not they can be seen
by our eyes. RFID solutions can thus significantly condense redundant inventory stock,
help to reduce inventory loss, and facilitate better quality assurance by providing the end
user with real-time product information.
Q : Will RFID technology ever replace the ever-present barcode?
SATO believes that RFID tags will not replace, but complement the ev
system. Given the growing popularity and viability of RFID, it can be expected that majority
of the industries using barcode technology will experience pressure to implement RF
(radio frequency) tagging systems to some extent, to complement or supplement barc
