3. What is RFID
ï” RFID = Radio Frequency IDentification.
ï” An ADC (Automated Data Collection) technology
that:
ï” Uses radio-frequency
ï” Does not require physical sight or contact
ï” Provide unique identification
ï” Other ADC technologies: Bar codes, OCR.

with RFID inside
an antenna,
printed, etched
or stamped
on a substrate
e.g. a plastic

6. RFID tags
ï”Tags can be attached to
almost anything:
ï” Items, cases or pallets of products, high
value goods
ï” vehicles, assets, livestock or personnel
ï”Passive Tags
ï”Semi passive tag
ï”Active Tags

9. RFID readers
ï” Reader functions:
ï” Remotely power tags
ï” Establish a bidirectional data link
ï” Inventory tags, filter results
ï” Communicate with networked server(s)
ï” Can read 100-300 tags per second
ï” Readers (interrogators) can be at a fixed point such as
ï” Entrance/exit
ï” Point of sale
ï” Readers can also be mobile/hand-held 07-02-2020

13. RFID advantages over bar-codes
ï” No line of sight required for reading
ï” Multiple items can be read with a single
scan
ï” Each tag can carry a lot of data
(read/write)
ï” Individual items identified and not just the
category
ï” Passive tags have a virtually unlimited
lifetime
ï” Active tags can be read from great
distances
ï” Can be combined with barcode
