Radio-frequency identification(RFID) is an Advance technology that uses radio-frequency waves to transfer data between a reader and a movable item to identify, categorize, tracking.
RFID is fast, reliable, and does not require physical sight or contact between reader/scanner and the tagged item.
- Requires a transceiver(Reader), antenna, and transponder(Tags).

Barcode Vs RFID
| |
Barcode Reader Require Direct Line of sight, using the laser technology.
Scan and read one tag at a time .
|
RFID does not require line of sight.
Scan and read Multiple tags Simultaneously.
|
Reading by Barcode takes much more Time. .
|
Reader can read tags much faster, appx. 20 Tags per seconds.
|
Human Intervention is required to scan a barcode .
|
Human intervention is overcome by RFID Tech..
|
Barcode can be affected by dirt, Moisture and packaging.
|
RFID tags are not affected by those conditions.
|
Less read range in comparisons to RFID
|
RFID tags have longer range than Barcode
|
Less Expensive
|
More Expensive
|
Barcode don’t have read/write memory
|
RFID have Read/Write memory
|
RFID Applications:--
- E-Passports(Ist introduce in Malaysia-1998)
For toll booths (or any “pay for entry” system)
Tracking Books in Libraries
Car keys, wireless entry and ignition
Animals Identification-- Hospital Patients

Why RFID Need in Libraries:-
Libraries have used RFID to replace the barcodes on library items. The tag can contain identifying information or may just be a key into a database. An RFID system may replace or supplement bar codes and may offer another method of inventory management and self-service checkout by patrons. It can also act as a security device, taking the place of the more traditional electromagnetic security strip.
RFID tags can be read through an item, there is no need to open a book cover or DVD case to scan an item, and a stack of books can be read simultaneously. Book tags can be read while books are in motion on a conveyor belt, which reduces staff time. This can all be done by the borrowers themselves, reducing the need for library staff assistance. With portable readers, inventories could be done on a whole shelf of materials within seconds.There are followings reason why rfid for library:-
• Fastest, easiest, most efficient way to track, locate & manage library materials
• Efficient Book circulation management.
• Automatic Check-in and Check-out.
• Library inventory tracking in minutes instead of hours.
• Multiple books can be read simultaneously.
• human intervention is overcome by this technology.
• Automated material handling using conveyor & sorting systems
How does RFID Works in Libraries:-
1) Firstly items-tag are scanned by reader;
2) Secondly in backend transmitted data coming through antenna (RF-wave) are being recognized by RFID-based system PC. It acts as a middleware communication gateway among items, reader and system database;
And at the end it filters out and store data in RFID-databases for checking the data fault and relevant operation.
