This question targets mostly the people that sell cameras. Sometimes the producer of a certain type of camera sells it together with a few accessories in a kit. I've done quite a few searches and I still don't know the answer.
I'm a developer working on an e-commerce site for a reseller. He asked me to write code that allows him to read the bar codes for his products. When he's dealing with a kit from a producer, he wants to read a single EAN for the kit and several serial numbers corresponding to each accessory. He's currently unavailable for a couple of weeks and I need this information: do the accessories themselves have distinct EAN numbers or do they match the camera's EAN? Can these accessories be sold separately?
