Laser Bar Code Scanning- Can be implemented now- Existing method- How reliable?

Image Based ID Reader- Can be implemented now- Reads number rather than bar code- How reliable?

RFID- Feasible in 2 years?- Most reliable method- Less chance of missing an item- Costly?

Camera Image Recognition- Feasible in 2 years?- Difficult to set up but easy to run thereafter- Preferred method if possible

DevelopmentTechnologyI researched into many technologies for the automatic scanning of items. Essentially, it could use any of these four methods as well as many more. I chose to use laser barcode scanning as it is existing technology, but if possible, camera image recognition would prove more reliable in future.

Conveyor BeltsI looked in to many possible ways of distributing items to different packpoints. I considered using an extendable curved belt to move between packpoints, but in the end chose to use rollers which can switch the angle that they transfer items. This allows items to either pass straight over or be directed sideways in to the packpoint.

Belt moves items into scanner

Laser bar code scanners scan the item from all sides

Roller plates direct items either straight on or angle in to PackPoint
