I am working with NFC in Android. I have done things with NFC tags and Android Beam, but I am wondering if is possible to communicate two Android phones with NFC without Android Beam.
I mean, I want to transfer some information, like a text or a URL using peer-to-peer in two Android phones, as if they were two NFC tags. I want to read and write this information in the other device, but the only way I have found to comunicate and trasfer data using P2P in Android is with Android Beam.
Is it possible?
PS. Sorry for mi english
No. It is not possible - if you want to use NFC bearer, only the SNEP/NPP over LLCP is possible (i.e. peer2peer mode).

I'm trying to send temperature and humidity data using arduino to a android smartphone via NFC. I set up the circuit using a DHT11 sensor to measure data, and RFID-RC522 module to read data when using an identified tag. I want to be able to see the data from the phone, when I read my NFC supported phone to the module.
I ask for your help in this matter.
Thank you in advance for your answers.
Unfortunately the MFRC522 chip is extremely basic and can only act as a reader, thus probably your only option is to use Host Card Emulation (HCE) on Android so that the Android phone emulates a Type 4 (ISO 7816) Tag.
But you will still have to do a lot of work on the Arduino to implement the the protocols needed, to have the MFRC522 to write data to the Android phone pretending to be a Tag.
If you used a more advanced NFC Chip like the PN532 you could reverse the roles and as the PN532 can emulate a Tag and thus the Android Phone could be the reader and just read values from the PN532 emulated Tag
Note I've not tried this myself, just my research in to a similar problem.
We have an Android app that writes data to a NFC tag using Android Beam. After deprecation of Beam in sdk 29, is there any alternative for data transference with a NFC tag?
Is it possible to use Google Nearby Share with a NFC tag?
I didn't found any documentation for it.
Google Nearby Share is Bluetooth or Wifi Direct as these were deemed by method to transfer data in the deprecation of Android Beam.
It should be technically possible to still transfer data via NFC without Android Beam, though there are some technical difficulties to over come.
One Device pretends to be a NFC Card with Host Card Emulation (HCE) and the other device reads/writes to it as if it was a normal Type 4 NFC card.
There are some complications if one device still has Android Beam but using the enableReaderMode NFC API to read/write to the Emulated Card should get around this.
I think some people of StackOverflow have tried this, I have not personally but the process of using HCE should be technically possible.
I am developing an app with which I transfer a vcard between two nfc capable devices. I am able to do it if both the devices have android beam. I want to know if it is possible to transfer information from an ICS device(Having android beam) to a gingerbread device(which does not have android beam)...Thanks in advance..
Android supports two modes for operating with NFC:
P2P -> Android Beam //
Tag Reader -> "Advanced NFC Framework"
If i'm not wrong, Android Beak is supported in Gingerbread too, so you shoudn't have to face any problem exchanging data between two Android NFC devices with Beam.
The second way, is only for making operations with Tags. Android does not support card emulation officially so this is not an option for you.
Hope this helps you.
I am just thinking about possibility to realize data sending/receiving between 2 or more NFC enabled smartphones. Is it possible or not? All I see about NFC is about interaction between NFC terminal/card and phone...
This is the nfc p2p mode. Android Beam is the "pre-installed" android nfc sharing app. BlackBerry Tag (O.S. 7.1) does the trick for BlackBerry. Nokia's nfc handsets already do it out of the box. I just don't know; What about tapping a nokia to an android, or android to blackberry, does it work? Feedback from users is hard to find yet.
Line one from: http://developer.android.com/reference/android/nfc/package-summary.html
Provides access to Near Field Communication (NFC) functionality, allowing applications to read NDEF message in NFC tags. A "tag" may actually be another device that appears as a tag.
Hope this answers your question :-)
I am working on Android application (Droid Incredible).
I am planning to read passive RFID tags using Android phone but I found that there is no slot for Android to connect to RFID reader.
After some research, I found out that I will have to get RFID reader which can send RF data over bluetooth to Android.
But I am not sure which company manufactures it or what will be cost of such RFID reader.
Is there any one who can help me or throw some light on this issue?
Thanks

Inorder to read RFID Passive tags using Android devices, Now there are Android devices with RFID integrated in it to read the Passive tags and you can customize your android application according to your requirement
If you want to build your own circuit for reading Passive tags and to get the tag data to your Android device, The best way is to use Arduino Microcontroller Boards. Using EM-18 and RC- 522 RFID modules integrated with Arduino, you can read the LF and HF Passive tags respectively. If tag reads, you can get the data either in serial monitor or display attached to the Arduino.
To get this RFID tag data to the Android device, the circuit which helps you is HC-05 Bluetooth Module which sends/receive to/from Android device.
Thanks
Siddhesh:
RFID is supported since Android 2.3 (GingerBread) but with an exception (if the brand handset has available the hardware to do that). On the most of the cases you can check on handset's cover a label like as NFC and so on.
I understand is established by RF (HF) and its purpose is to replace: bar codes, QR codes and bluetooth and it looks like that is not too fast to permit a big amount of transfer information.
is there any other tips related to implement class and objects to perform on Eclipse Proyect, I will Thank You.
