Invention 35: Bar Codes

On most occasions, when I shop in South Africa, there are bar codes which will not be scanned the first time, and often enough, will not be scanned at all. This invention proposes methods which could work better. For example, a larger, fluorescent bar code, which need not be visible on a product, so in a sense could take up zero space. One could also scan magnetic bars, or conductive bars.
