I want to send out some items for test. There are a slightly different variants of the item, so I'd like to put a serial number on the back so if someone phones to report a problem, question or suggestion, I can lookup which item it was. There are less than 12, so not worth getting braille sheets made up. I have this Dymo 3d labeller, the imprint is quite tactile and well spaced. Would people generally find it acceptable to have a Dymo sticker with: 1 0 1 0 for serial number 10. 1 1 1 0 for serial number 13 etc Not that it matters that it's binary, but this would allow me 16 distinct numbers, and to a non-braille person like me, those two numbers felt distinctively different. Just trying to gauge a group opinion on a quick temporary solution to a simple problem without annoying potential testers!
