RST is an input for reset and power-down. But remember that connecting it to the 5V pin will probably destroy your module! You can connect it to the 3.3V output from your Arduino. This can be anywhere from 2.5 to 3.3 volts. It consists of a microchip that stores and processes information, and an antenna for receiving and transmitting a signal. Whereas the tag is usually a passive device (it does not have a battery). What is RFID technology and how does it work?Īn RFID or radio frequency identification system consists of two main components, a tag attached to the object to be identified, and a reader that reads the tag.Ī reader consists of a radio frequency module and an antenna that generates a high frequency electromagnetic field. It is low power, low cost, very rugged, easy to interface and extremely popular among hobbyists. You no longer need to wait for someone to ring each item in your cart one by one Now with the help of RFID tags attached to the items, every item in the cart will be detected and ringed almost instantly.įor most of our RFID based Arduino projects, the RC522 RFID reader/writer module is a great choice. With an RFID based walk-through automatic checkout solution, you can fill up your cart and walk right out the door. Gone are the days when people waited in long checkout lines at the grocery store, thanks to RFID technology.
