Better than bar-coding, but not RFID

What would happen if you crossed an RFID system with a traditional bar-coding set-up? It probably would look and act a lot like a Visidot system.
The Visidot, essentially, is the development in bar-code readers. But those developments seem to bring it closer to capabilities and functions of RFID technology. While Visidot’s primary image identification system involves color-based symbols, it’s also equipped to read 2D bar codes.
But it also offers more functionality than standard bar-code systems.
For instance:
Go for the long one — Visidot has much broader and longer scanning range, up to 150 meters (about 450 feet).
Any which way is up — traditional bar-code scanners can only read bar codes if they’re accessibly oriented.
Done in a flash — Visidot proponents say a full pallet of bar-coded cases can be read in one flash, which takes about a second.
While the Visidot still requires a line of sight — giving RFID one advantage — the new system can read multiple bar codes at a time.
Example: A pallet of goods with unique serial numbers is assembled. A sheet listing those serial numbers is printed and attached to the pallet. When a Visidot reader passes over this pallet, all of the serial numbers are captured for accuracy comparison.
One more advantage over traditoinal bar-code reading: If there’s a damaged bar code, the Visidot reader will detect it and inform the system operator.
