| Your choices are... | |||
| Passive | An RFID tag without a battery. When radio waves from the reader reach the chip’s antenna, it creates a magnetic field. The tag draws power from the field and is able to send back information stored on the chip. | ||
| Semi-passive | Similar to active tags, but the battery is used to run the microchip's circuitry but not to communicate with the reader. Some semi-passive tags sleep until they are woken up by a signal from the reader, which conserves battery life. | ||
| Active | An RFID tag that comes with a battery that is used to power the microchip’s circuitry and transmit a signal to a reader. Active tags can be read from 100 feet or more away. | ||
| Search Logic: | All products with ANY of the selected attributes will be returned as matches. Leaving all boxes unchecked will not limit the search criteria for this question; products with all attribute options will be returned as matches. | ||

| Frequency: | RFID products use low, high, ultra-high and microwave frequencies. Each frequency has advantages and disadvantages that make them more suitable for some applications than for others. | ||
| Search Logic: | User may specify either, both, or neither of the "At Least" and "No More Than" values. Products returned as matches will meet all specified criteria. | ||
| Memory: | The amount of memory controls the amount of data that can be stored on a tag. | ||
| Search Logic: | All matching products will have a value greater than or equal to the specified value. | ||
| Read Rate: | The maximum rate at which data can be read from a tag expressed in bits or bytes per second. | ||
| Search Logic: | All matching products will have a value greater than or equal to the specified value. | ||
| Detection Range: | The distance from which a reader can communicate with a tag. Active tags have a longer read range than passive tags because they use a battery to transmit signals to the reader. With passive tags, the read range is influenced by frequency, reader output power, antenna design, and method of powering up the tag. | ||
| Search Logic: | User may specify either, both, or neither of the "At Least" and "No More Than" values. Products returned as matches will meet all specified criteria. | ||
| Operating Temperature | The range of temperatures through which the RFID product is designed to operate. | ||
| Search Logic: | User may specify either, both, or neither of the limits in a "From - To" range; when both are specified, matching products will cover entire range. Products returned as matches will meet all specified criteria. | ||
