6. Challenges in Bar Code Scanning
Separate Device to scan the actual bar code as constructed
Scanning in Bright Sunlight, Filtered Light and Shade
Location of Bar Codes on Pipe and Fittings
Stick Pipe – Only one bar code
Insufficient Information in the Standard to support complete mapping at Questar
