Checking your phone for NFC capabilities, enabling NFC, downloading an NFC reader app, adding your card information, and using your phone for NFC transactions are the key steps to leverage this technology.
By understanding the fundamentals of RFID technology, preparing your Android device, setting up the RFID reader app, and implementing best practices, you can effectively read RFID tags and harness the power of this technology.

You will need a rooted device and NFC Card Emulator Pro by Yuawnofei. It is a paid app available on Play store. There are limitations on the type of cards that can be emulated. Furthermore, not all devices and roms are compatible. You're better off getting a dedicated RFID card reader and some fobs.
NFC enabled phones can ONLY read NFC and passive high frequency RFID (HF-RFID). These must be read at an extremely close range, typically a few centimeters. For longer range or any other type of RFID/active RFID, you must use an external reader for handling them with mobile devices.Is it possible for an Android application to send a previously stored RFID card ID to a NFC reader? The aim would be to use an Android device to enable access to a room instead of a physical RFID card. How to make my Android device act as a NFC tag? Example: since I can read and get the hexadecimal codes from my NFC door card, I'd like to make my smartphone act as a NFC card, so that, if I forget my door card, my smartphone could serve as a NFC tag. How to do this? As a rule of thumb, RFID readers (125kHz and 13,56MHz standards) work for the distance that is simmilar to the diameter of it's antenna coil. But if you make the antenna coil bigger, you will eventually loose coupling between tag and reader.

Yes, the NFC circuit in a smartphone can read RFID tags that operate at 13.56 MHz. I personally have never seen any device capable of reading a small passive tag with a range greater than about 10cm. For long range applications you may be interested in UHF tags like the ones used for electronic road tolls.This article will guide you how to integrate RFID NFC Card Reader in your android application. By understanding the fundamentals of RFID technology, preparing your Android device, setting up the RFID reader app, and implementing best practices, you can effectively read RFID tags and harness the power of this technology.
