RFID & BARCODE COMPARISON
Advantage of RFID use vs BARCODElabel
|Read Rate||High throughput. Multiple (>100) tags can be read simultaneously.
Passive UHF RFID:
|Very low throughput. Tags can only be read manually, one at a time.
Several inches up to several feet
|Line of Sight||Not required. Items can be oriented in any direction, as long as it is in the read range, and direct line of sight is never required.||Definitely required. Scanner must physically see each item directly to scan, and items must be oriented in a very specific manner.|
|Read/Write Capability||More than just reading. Ability to read, write, modify, and update.||Read only. Ability to read items and nothing else.|
|Durability||High. Much better protected, and can even be internally attached, so it can be read in very harsh environments.||Low. Easily damaged or removed; cannot be read if dirty or greasy.|
|Security||High. Difficult to replicate. Data can be encrypted; password protected, or include a “kill” feature to remove data permanently, so information stored is much more secure.||Low. Much easier to reproduce or counterfeit.|
|Technology||RF (Radio Frequency)||Optical (Laser)|
