Answer: Step 1: To “register” a bar code: First thing you would do is personally assign the bar codes to your products, this is done by you/your company and you would have to keep your own records of these associations. Many use spreadsheets or their own POS system, either way, we recommend having your records backed up in case your computer crashes. 

Step 2: Then you register/record this data at the store it will be sold at. Each store has its own internal, private database (aka: Point Of Sales System). This means that every new store/site you approach won’t know anything about your product until you input the data into their private P.O.S. system. 

Step 3: Repeat for all new stores/venues/distributors you approach to sell your barcoded products.
