Tags are available with storage capabilities from 512 bytes to 4MB. It largely depends on vendor and whether the tag is passive or active. Data stored in a tag will be determined by the application of the system and appropriate standards. For example, a tag could provide identification for an item being manufactured, goods in transit, or even the short-range location and identity of a vehicle, animal, or individual. This fundamental data often is referred to as a "license plate code," similar to the information that is stored on a bar code label. When linked to a database, additional information may be accessed through the reader such as item stock number, current location, status, selling price, and batch code. Alternatively, an RFID tag may carry specific information or instructions immediately available upon reading, without the need to reference a database to determine the meaning of a code. For example, the desired color of paint on a car that is entering the paint assembly area on the production line, or a manifest to accompany a shipment of goods.
