Guys can yu suggest me some real time problems which could be resolved by using rfid tags

 

Well if you linked your name to tag it no who you are in real time .
There good to let you go swimming where I live. They let you in the workout room and the laundry room.
You could use them to log into a computer.

 

Tracking the location of medical equipment inside, or I suppose outside if it's been nicked, of an hospital.

 

I have an RFID tag on each of my cats, and an RFID reader coil around the cat door entry, so I can trigger the door to unlock when the correct cat is there. The RFID tag is a lot lighter than the collar magnet for magnet-triggered doors, and I can track which cat goes in and out at what time.
