As a home hobbyist, the most important thing comes across your mind is, what project you can do for the upcoming weekend. In order to avoid spending your weekend doing nothing but daydreaming, you might want to try this RFID activated phone system.
By the way, RFID is a short acronym for “Radio-frequency identification”. Normally, RFID is an object typically referred to as an RFID tag and being applied to a product, animal or person for the purpose of identification and tracking using radio waves. Some of the tags can be read from several meters away and is totally beyond the line of sight of the reader!
The main purpose of this project is to create a phone, where is enable the user dials the desired number based on placing a picture on or near the phone. In general, the device can be worked like many other iphone apps and allows the user to call a person by pressing their picture on your phone!
The RFID reader is actually a very simple-to-use device and can be connected to an Arduino easily. If you want to eliminate multiple reads, then you should consider put a delay, soon after a delay has been reading.
