Trovan - About RFID
What are the limitations of barcode?
Tag size. Not suitable for extremely tiny items or tag dimensions.
Scan angle. Barcodes require line-of-sight scanning, without obstructions.
Tag orientation. Barcodes require line-of-sight scanning. You cannot read them through objects, paint, mud or dirt.
Harsh environments. Barcodes can be scratched, scuffed, or corroded. Abrasion and direct impacts deface barcodes.
Bright sunlight and reflective surfaces.
Water droplets.

Sensor Sense: RFID for smart position sensing | Machine Design
Robert Repas 1 | Nov 04, 2010
In most applications, radio-frequency-identification (RFID) systems are used to store product and process data on, or retrieve it from, a special RFID tag using wireless technologies. Power to operate the electronics in the tag comes from the RF energy of the interrogating transmitter. When powered, the tag transmits the programmed identifying information to the receiver. But if you look at RFID tagging on a more-fundamental level, it's essentially a smart proximity sensor.
A proximity sensor detects the presence of a piece of metal and...
