Can I copy my NFC ID badge and use my phone instead of my card? My College decided to .A quote from the docs. Android 4.4 and higher provide an additional method of card emulation that doesn't involve a secure element, called host-based card emulation. This allows any Android application to emulate a card and talk directly to the NFC reader. This topic describes how host-based card emulation (HCE) works on Android and how you can . So eventually, I want to replace the NFC card with the Android device. This is my code for reading the ID from the card: TextView txt; NfcAdapter nfcAdapter; @Override. public void onCreate(Bundle savedInstanceState) {. super.onCreate(savedInstanceState); setContentView(R.layout.activity_main); txt = (TextView) findViewById(R.id.textView); 6. Its possible to make Android device behave as an NFC Tag. Such a behaviour is called Card Emulation. Card emulation can be host-based (HCE) or secure-element based (CE). In HCE, an application running on the Android main processor responds to the reader. So, the phone needs to be ON.
Thus you can use NFC as a RFID device the distance would still be limited to the 4 inches by the hardware in the phones. // edit. you could instead use the new Bluetooth 4.0 Protocol. The Setup-Time between Communication Partners is as fast as NFC (<0.1s) (in contrast to Bluetooth 2.1 with almost up to 6s)
12. Android 4.4 introduced Host-based Card Emulation (HCE). As you know, all NFC cards come with a fixed card ID (NfcAdapter.EXTRA_ID). My office door access usually detects the NFC card ID for the authorization. After flashing my phone to KitKat, I tried to scan my phone with the access reader.

This works without rooting the phone. I believe that some (not all) phone hardware might be able to emulate one other type of Tag if you have rooted the phone and know the non public API to access the hardware in the right manner (not confirmed).
First is understanding that RFID is very generic term. NFC is subset of RFID technology. NFC is used for prox card, credit cards, tap and go payment system. Your phones can read and emulate NFC (Apple pay, Google pay, etc.), if they support NFC. NFC is very short distance and low power - which is why you see tap and go type usage. 1. I think your problem is that the MFRC522 RFID reader is a very basic/old design and really only supports MIFARE type cards (which are the non standardised original card format). While Host Card emulation uses ISO/IEC 14443A (mostly) as a base it uses other higher level protocols to emulate a NFC Type 4 card which is not supported by that . 6. Yes it's possible meanwhile to prevent cloning a Tag. There is a new tag called the NTAG 413 - which can generate a new NDEF message every single time you tap it. (using AES krypto) This way it's not necessary to have a seperate app installed on your smartphone.
