RFID is very useful Technology for Blind man to Identify the things like Buses, Trains, Railway Station and virtually anything we can think about. We can embed the RFID reader in Blind man stick and put the RFID tags on other things to identify them for the blind man and blow a siren or a prerecorded voice for each item which has RFID tag on it and is in the database of RFID reader of the blind mans stick.
Radio-frequency identification (RFID) is an automatic identification method, relying on storing and remotely retrieving data using devices called RFID tags or transponders. The technology requires some extent of cooperation of an RFID reader and an RFID tag.
An RFID tag is an object that can be applied to or incorporated into a product, animal, or person for the purpose of identification and tracking using radio waves. Some tags can be read from several meters away and beyond the line of sight of the reader.
This kit includes Low Frequency RFID Reader and tags working at 125 khz frequency to fetch the information from the vehicle/train/railways station or any object to process it through microcontroller. Then microcontroller will receive the information from RFID Reader and detect the object from RFID tags connected to object and play the prerecorded sound for that particular object. The amount deducted will be displayed on the LCD display along with the Vehicle number. Each vehicle will have a unique RFID tag to identify it.
