My understanding is that getting barcodes to stick on curved surfaces, let alone read them, is still an issue. I tend to agree with all the points brought up by Ron and would suggest you tak a look at the numbering techniques brought up earlier in this forum. People had some very helpful suggestions. I woud encourage you to use the thee part numbering system which has become a standard in the Museum world. Keep your questions coming… this is a great place to find answers!
