Every system has to start with selecting an RFID tag that will perform well given your reading requirements, size constraints, and application type. A tag consists of two parts: the chipset and antenna. The chipset stores the unique data for the tag, determines the amount of information it can store, and the available security features. The antenna allows the chip to receive power and transmit information. Normally, the larger the antenna the better range you will get. There are a variety of chipsets and antenna designs which are designed to perform in all types of applications.
