In this tutorial, the presenter will be giving you a tutorial on radio-frequency identification (RFID), how it works and how to make an Arduino based RFID door lock. It’s a non-contact technology that’s broadly used in many industries for...
RFID is a non-contact, automatic identification technology that uses radio signals to identify, track, sort and detect a variety of objects including people, vehicles, goods and assets without the need for direct contact or line-of-sight contact (as found necessary...
The main objective is to design a MODEL ATM machine using RFID and GSM technologies. Here we design a model of how really ATM machine works, with some limited features. Also in this model we use wireless smart card...
Most educational institutions' administrators are concerned about student irregular attendance. Truancies can affect student overall academic performance. The conventional method of taking attendance by calling names or signing on paper is very time consuming and insecure, hence inefficient. Radio...
Radio-Frequency Identification (RFID) is an automatic identification method, relying on storing and remotely retrieving data using devices called RFID tags or transponders. RFID is a technology that incorporates the use of electromagnetic or electrostatic coupling in the radio frequency(RF)...
Radio-Frequency Identification (RFID) is a technology that uses radio-frequency electromagnetic fields to transfer information from a tag to RFID reader for identification purposes. The tags do not require battery power. They derive power from the electromagnetic field generated from...
In this article we describe how to create a game station entry card so that a player can enter the game station only once using that card. A radio-frequency identification (RFID) reader, a few RFID tags, an ARM LPC2138 development...
Will LTE-U destroy Wi-Fi? There seems to be a battle going on between the proponents of Wi-Fi and those keen to introduce a new technology—LTE in Unlicensed Spectrum (LTE-U). Besides the expensive spectrum that companies like Airtel, Reliance and Vodafone...
Radio-frequency identification (RFID) is an automatic identification method wherein the data stored on RFID tags or transponders is remotely retrieved. The RFID tag is a device that can be attached to or incorporated into a product, animal or person...
