RFID Mobile Charging System


Ever been in a situation when you are having a very important conversation and your phone’s battery just dies? Ever made an important document/presentation, almost about to finish and save but the phone turns OFF and POOF goes the document? These things happen all the time. Our lives have become so hectic that, we just can’t get enough from our phone’s battery. It might happen that many a times you don’t even get a chance to charge your phone to last a day. At such a time, our project RFID mobile charging comes to the rescue. Battery about to die, no need to worry; our system can give you those few crucial minutes at just a swipe of a card.
This project features an RFID card reader, to recognize a user. Once a valid user has been identified the system then starts recharging the mobile. Before a user can charge his/her phone, he/she has to register their respective card/cards. Our system can register 3 users at one time. After registering, the user is credited 5 minutes of mobile charge. So now, the user must connect a phone to the charging port and swipe the card. Once identified as a valid user the system starts charging the phone. Along with charging, the system also keeps a record of how much charging time the user has got left, this remaining time is displayed on an LCD. If the user is running short on time and needs to unplug the phone, he/she can swipe their respective card and the charging will stop. The remaining time of the user will be saved by the system and the user can charge his/her phone later. Another important feature of this system is Extra Charge; incase a user needs more charge, this can be done quite simply. A button is provided on the system for Extra Charge, by pressing this button the user gets an additional credit of 5 minutes over the remaining charge time. Furthermore, if an Invalid user tries to recharge his/her phone by swiping the card; the system tries matching it with the valid IDs stored. But since this user isn’t registered, the system shows Invalid user and doesn’t credit any charging time.
So in this way, we have made a system which enables the users to charge their phones for crucial moments at very affordable prices. So say goodbye to dying batteries and say hello to RFID mobile charging.
