Scale Barcode Breakdown - Price	This shows the starting character and length of the price for scale items in a barcode. For example, Product Code is 2,4 and Price is 7,4 and the entire barcode is 13 digits in length. From this setup we know that the product code starts from the 2nd digit and is 4 characters in length and price starts from the 7th digit and is 4 characters in length. For example, onions are setup in the Product Master as a scale item with code 1001 priced at $3.94/kg. This item will be scanned in POS as XppppXppppXXX where X denotes a zero, 1st set of p is product and 2nd set of p is price. If a customer buys $10.68 of onions, the Barcode format printed by the scale is: 0100101068000.
