. . . . . . . . tags contain battery and transmit signals autonomously

Acitve RFID
Passive RFID
Battery-assisted passive RFID
Battery-assisted RFID

The correct answer is: A. Active RFID

Active RFID tags contain a battery and transmit signals autonomously. They are more expensive than passive RFID tags, but they have a longer range and can be read even in difficult conditions, such as when there is a lot of metal or water present.

Passive RFID tags do not contain a battery and must be powered by the electromagnetic field emitted by the reader. They are less expensive than active RFID tags, but they have a shorter range and can only be read in good conditions.

Battery-assisted passive RFID tags are a type of passive RFID tag that contains a small battery. This battery is used to power the tag’s internal circuitry, which allows it to transmit a stronger signal than a passive RFID tag. This makes battery-assisted passive RFID tags more reliable than passive RFID tags, but they are still less expensive than active RFID tags.

Battery-assisted RFID is a type of RFID system that uses a battery to power the tag’s internal circuitry. This allows the tag to transmit a stronger signal than a passive RFID tag, which makes it more reliable. Battery-assisted RFID is often used in applications where reliability is important, such as asset tracking and access control.
