RFID stands for radio frequency identification. This article helps you understand more about an RFID reader and tag – how they look, how they operate, how to use an RFID reader/tag and different other applications using an RFID reader. All these projects make use of an RFID reader and an RFID tag. We have also published simple RFID reader based projects like a Simple RFID Door Lock. We have published many interesting projects using an RFID reader module – like RFID Attendance Management System, or RFID based Access Control System. TM_ILI9341_Puts(90, 310, 'stm32f4-discovery.This article is developed as an ultimate guide on RFID reader module and RFID tag – and explains how it works. I read them with program below, and write this hereĠx43, 0xdc, 0x52, 0xb6, 0x7b //My card on my keys * Keil project for MFRC522 RFID Tilen Keil uVision 5 Detection distance was about 10cm from receiver. I got this working on STM32F429 Discovery board with SPI communication and display data on LCD on board. To get this to work, you also need RFID cards with same working frequency (included in packet from ebay).

I got it on Ebay almost for free with 2 RFID cards included.

Source: For that I used Mifare RC522 RFID reader from NXP. Unlike a barcode, the tag does not necessarily need to be within line of sight of the reader, and may be embedded in the tracked object. Battery powered tags may operate at hundreds of meters. Others use a local power source such as a battery, or else have no battery but collect energy from the interrogating EM field, and then act as a passive transponder to emit microwaves or UHF radio waves (i.e., electromagnetic radiation at high frequencies).

Some tags are powered by and read at short ranges (a few meters) via magnetic fields ( electromagnetic induction).

The tags contain electronically stored information. Radio-frequency identification (RFID) is the wireless non-contact use of radio-frequency electromagnetic fields to transfer data, for the purposes of automatically identifying and tracking tags attached to objects. In this library I’m talking about RFID ( Radio- Frequency IDentification).
