Why Use RFID
Advantage of RFID use vs BARCODElabel
| RFID | Barcode | |
| 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) |
