RFID technology is similar to the barcode in that way except the fact that RFID tags could be read from much more distant line of sight. RFID tags contain data (information) that could be collected by RFID readers using radio waves. RFID (short for radio-frequency identification) is a technology that digital data is encoded to “RFID tags” or smart labels can be read by an RFID reader, using electromagnetic fields. Tutorial Contents What is the RFID Technology and How It Works RDM630 RFID reader module, antenna (generally comes with the RFID reader), Breadboard, Jumper cables.MFRC522 RFID Arduino library ( Download here).Arduino UNO or equivalent microprocessor.How to apply RFID reader project using the library functions.How to use ”MFRC522 RFID” library and how to use Its functions.How to install “MFRC522 RFID” library to Arduino IDE.General knowledge about RFID technology.I will show you how to install the library to Arduino IDE and make an example project with the library, throughout this tutorial while giving information RFID technology and Its working principle.
This is a tutorial of an open source Arduino library, which lets you turn your Arduino to a “RFID Reader”, with a MFRC522 RFID reader module which reads and saves RFID cards information.
