It takes great pains to control a great deal of parts.
Need to physically check records of fixtures in the field
Effect of two-dimensional code system:
It is possible to find out where fixtures are swiftly.
Auto Recognition (scanning) can be done for even tiny fixtures using 2D codes.
It is possible to check fixture data without referring to the data base.
Duplicated checks can be gotten rid off.
