i. No line-of-sight: To read or write RFID tags doesn’t require line of sight.

ii. Robust: Because RFID systems do not need to be visible, they can be encased within rugged material protecting them from the environment in which they are being used. This means they can be used in harsh fluid and chemical environments and rough handling situations.

iii. Read speed: Tags can be read from significant distances and can also be read very quickly - for example, on a conveyor.

iv. Reading multiple items: A number of tagged items can be read at the same time within an RF field. This cannot be done easily with visual identifiers.

v. Security: Because tags can be enclosed, they are much more difficult to tamper with. A number of tag types now also come programmed with a unique identifier (serial identification) which is guaranteed to be unique throughout the world.

vi. Programmability: Many tags are read/write capable, rather than read only. This means that information can be written to the tag.
