Answer 1

Hello!

Answers:

A. Can be used in inventory management

TRUE

As using RFID we can track the stock in inventory , by attaching passive RFID tag to the item we can get the details of item in the inventory, so this way RFID is used in inventory.

B. Tolltag is an RFID transmitter

TRUE

FastTag is example of tolltag RFID, where when vehicle is passing through tollgate RFID reader in tollgate reads the data from the RFID of the car and checks the balance available in the tag and takes tha action depending on that

C. Sending device requires power to be applied in order to transmit.

FALSE

Sending device don't require power always because we have two types of tags 1.active RFID tag and 2.passive RFID tag

Where active tag requires fhe power by means of battery or any other source

But passive tag doesn't require Power the power gets transferred from reader and then information is transmitted back by the tag.

D. Requires a reader device which receives radio signals produced by a sending device

TRUE

Definitely we require a reader , the reader will turn on the tag and tag will have antenna and the radio signals is transmitted through antenna , in that all the data is transmitted.

E. Used to identify and display radio station and media playing on radio.

FALSE

We don't get any information in the media playing on radio so we can't display the radio station location.

Always tag will hold the data or information , which is read by RFID reader and reader will give to the computer or any other device

Hope this helps and clear.
