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) |
