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 . Then using reflection, enable mifare emulation. Then using a mifare reader/writer (hid 6055b), I encode the data (sectors and blocks, in my case sector 1) onto the phone. In essence, I treat the phone as a mifare ID card. That is, i copied my id card to the phone. You can't programmatically set this. NXP owns mifare. 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.

1 Answer. Sorted by: 2. Nothing in Android has changed, it's still not possible to emulate a non standard Mifare card unless the firmware of a specific chipset has the feature and you can hack it to enable it. It's probably got even worse as there are more chipset suppliers for NFC in Android now and most of these don't even support reading . In order to emulate a card with the phone, you need a secure element (smartcard chip on the phone or the SIM card in your phone), and you need the NFC chip in your phone to route card emulation APDUs to this secure element (this is probably what the patch you are referring to is doing). There are ways to do card emulation in an Android .

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. You can get some decent readers from a lot of manufacturers by .4. The NFC part is very simple but the unlocking part is more complicated than you think. Unlocking your computer should never be done programmatically because if your program can do it, then so can others. Not to mention that this 'program' is going to act based on communication between a remote server and itself. Most of the NFC enabled Android phones have low level capacity to emulate cards. The NXP chip that is used in the phones as well as the android kernel supports card emulation. However, the high level Android API does not expose these features most likely because some obvious security problems with such feature.

With host-based card emulation (HCE) in Android 4.4 you can only emulate the ISO/IEC 14443-4 protocol. More specifically you can only emulate application structures according to ISO/IEC 7816-4 (thus card emulation applications need to be selected though an AID). Moreover, the API doesn't give you any means to specify if card emulation should be . 2. First off a NFC UID is not designed to be Unique or have any level of security attached to it. It just has to be likely to be different when multiple Tags are in range. Thus a lot of phones now generate a random UID as a security feature to prevent it's use in tracking phones.A quote from the docs.
