RFID Vs Barcode








































RFID
Barcode
Read Rate
High throughput. Multiple (>100) tags can be read simultaneously.
Very low throughput. Tags can only be read manually, one at a time.
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.
Human Capital
Virtually none. Once up and running, the system is completely automated.
Large requirements. Laborers must scan each tag.
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 through 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.
Event Triggering
Capable. Can be used to trigger certain events (like door openings, alarms, etc.).
Not capable. Cannot be used to trigger events.
