Forecasting is a way of using historical data and future business plans to forecast the future. A forecast will reveal where the business is going to.

Transponder technology for the contactless recognition of objects. The heart of this technology is the so-called RFID tag, a small computer chip with a miniature antenna. It can be used on transport and goods packages as well as sales units and products. When the chip receives the radio signal from a reading device, it automatically transmits the stored data wirelessly. Transmission is based on radio frequencies. The tags are passive; they do not require any battery or maintenance.
