RFID and Barcode
Nowadays, more and more field use RFID instead of a barcode, Like hygiene, library, Car track.
Both RFID and Barcode are used for storing information, but there is too much difference:
For the barcode, the scanner must direct to the bar code, however, the RFID just close the label or near it, is OK;
RFID label can support long distance, several meters or even more, the barcode could not longer than 5 meters;
RFID reader can read labels faster, hundreds at one times;
For the barcode must put the scanner to the right place and right distance, need several seconds;
On the other hand, the barcode cannot be dirty, damaged, covered by others. RFID would be more durable, not influenced by the environment, also can be embody in any material any shape;
Barcode cannot write data, only a serial number for your scan, for RFID you can write data according to your needs;
However, RFID would be more expensive than Barcode.
