2D Code Readers
Readers are available from a number of different sources.
The generic requirement is that they should be able to decode QR-codes and have a resolution of 0.1mm (5mils).

At CERN, we have two types of code reader that work:
    Manufacturer: Denso, Type: QS-20P
    Manufacturer: Data Logic, Type: Lynx D302E (Less highly recommended, difficult to judge focal distance)

Other code readers are available from (this is not an exhaustive list):
    Manufacturer: Code Corporation, Type: Code Reader 2.0 (CR2)
    Manufacturer: Hand Held Products, Type: Imageteam 4410HD (No Longer recommended, difficult to use routinely)
