Arduino RFID technology works by using electromagnetic waves in the radio frequency spectrum for wireless communication and data transfer between RFID tags and readers. From supermarket anti-theft ...

This project demonstrates how to use an RFID RC522 module with an Arduino to authenticate RFID cards. The system turns on a green LED if an authorized RFID card is scanned and turns on a red LED and ...

Radio Frequency Identification is widely used in contactless payment cards, National Highway Tollgate systems, and in security passes. By integrating an RFID reader with an Arduino, you will be able ...

[Pierre] recently bought his first car and decided to make his own RFID electric starter for it! An Arduino Nano controls two relays which in turn can turn the car on, start it, and turn it off.

The use of Radio Frequency IDentification (RFID) technologies is growing. Many different applications are implemented in various sectors, and used for very different purposes. RFID enables wireless ...

The radio frequency identification (RFID) system used for the identification and tracking of objects makes use of an RFID reader and a tag. The main parts of the authentication system include the ...

Electronics developer and Kickstarter serial entrepreneur Patrick Thomas Mitchell who we have featured numerous times here on Geeky Gadgets has once again taken to the crowdfunding website with the ...

For starters, you need a pre-wired NFC RFID module as the key hardware. NFC and RFID projects have become a huge trend, but many modules are pricey for electronics hobbyists and need a complex setup.

Connect the components as per the wiring diagram. Ensure the RFID module is properly connected to the Arduino's SPI pins. Connect the I2C LCD display to the Arduino's I2C pins (SDA and SCL). Upload ...
