The term 'synaesthetic' can be used to broadly describe the different kind of association that the ancient Greeks made between the five senses. 'If colours are the external manifestations of objects, then the perception of that colour can tap into other ideas such as smell, liquidity, saturation, touch, texture.'. In what we would tend to think of as purely visual, the ancient Greeks brought other senses into play.
Universal Product Code. The Universal Product Code (UPC) is a barcode symbology that is widely used in the United States, Canada, United Kingdom, Australia, New Zealand, in European and other countries for tracking trade items in stores. UPC (technically refers to UPC-A) consists of 12 numeric digits, that are uniquely assigned to each trade item.
The next five digits -- 00039 -- are the item number. A person employed by the manufacturer, called the UPC coordinator, is responsible for assigning item numbers to products, making sure the same code is not used on more than one product, retiring codes as products are removed from the product line, etc.PC stands for Universal Product Code. UPC bar codes were originally created to help grocery stores speed up the checkout process and keep better track of inventory, but the system quickly spread to all other retail products because it was so successful.
