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 ...
In this tutorial we are going to design a system to read the ID of RFID cards. RFID stands for Radio Frequency Identification. Each card has a unique ID embedded in it. These systems have many ...
All the calculations we've performed so far assume that a wave leaves the antenna and strikes the tag, interacting with no other objects. This kind of calculation is very sensible if the tag and ...
Passive and semipassive RFID tags do not use a radio transmitter; instead, they use modulation of the reflected power from the tag antenna. Reflection of radio waves from an object has been a subject ...
I recently wrote a German tutorial (https://plantprogrammer.de/esp32-rfid-and-mqtt/) that describes on how to use an ESP to publish UIDs of RFID-tags into an MQTT ...
ติดตั้ง library ของ RFID module โดยพิมพ์คำว่า MFRC522 ในช่องค้นหา library แล้วเลือกติดตั้ง "MFRC522 by GithubCommunity" เวอร์ชัน 1.4.10 ...
Objectives: This session will provide an overview of the status of RFID technology and present efforts by several organizations towards global NRFID standards.
Abstract: Radio frequency identification (RFID) offers tantalizing benefits for supply chain management, inventory control, and many other applications. Only recently, however, has the convergence of ...
