In this activity you will be using a circuit board based on the MFRD microcontroller. The microcontroller works by using a To communicate with the circuit board we are going to be using the Serial Peripheral Interface SPI which allows transfer of data between the computer and the data collecting device. There are four separate connections to communicate with the device. These connections are:. There is an element14 ad at , but the narrative picks back up at explaining with Arduino rather than Raspberry Pi. Then again at he talks about Raspberry Pi.

Posted by Harry Mafukidze Raspberry Pi 1. Radio frequency identification RFID devices are an essential part of almost all physical security systems. RFID cards and card readers are used to restrict access to buildings or rooms. But most RFID devices usually operate at All RFID cards and tags have two components — an IC that stores the unique identification number and a coil of wire that acts as the radio frequency antenna:. The RFID card reader also has a coil of copper wire. This coil creates a magnetic field when a current flows through it. The card reader can then read the unique identification number on the card. This is useful for creating new RFID cards. You also need to install pip3 with this command:. Our first step will be to read the information on the RFID card. To do this, connect the components as shown in the diagram above.

To do this, connect the components as shown in the diagram above.

Last Updated on 2nd September by peppe8o. Their technology is so mature that they are today reliable components and easy to use. The RC module with Raspberry PI can bring to your hands this technology with a few steps and a cheap budget. It uses radio waves to transmit signals that activate the tag. Once activated, the tag sends a wave back to the antenna, where it is translated into data. The tags integrate a circuit, an antenna and a substrate.
