ndef nfc tags In order to understand NFC, you need to know about the NFC Data Exchange Format (NDEF), which is the lingua franca for NFC devices and tags. In this chapter, you’ll learn about the structure of NDEF and the records it carries.
Yes. Though not a phone, but a pseudo phone device, absolutely. This is an attack where one phone is near a contactless card and it transmits the card information to a second phone .

This document describes the basic NFC tasks you perform in Android. It explains how to send and receive NFC data in the form of NDEF messages and describes the Android framework APIs that support these features. For more advanced topics, including a discussion of working with non-NDEF data, see . See moreAndroid-powered devices are usually looking for NFC tags when the screen is unlocked, unless NFC is disabled in the device's Settings menu. When an . See more

In android all NFC devices are detected and processed as PICC devices, android.nfc package provides access to Near Field Communication (NFC) functionality, allowing applications to read NDEF message in NFC tags. NFC tags like Mifare Classic cards can be configured as NDEF tags, and data written to them by one NFC device (NDEF Records) can be understood and accessed by any other NDEF compatible device. NDEF messages can also be used to exchange data between two active NFC devices in "peer-to-peer" mode. The device you are using (in combination with that Android version) does not 1 have support for NDEF on NfcV tags. Therefore, you can't format the tag in a way that the NDEF message will be detected by your Android device.NFC Data Exchange Format (NDEF) NDEF is a standardized data format specification by the NFC Forum which is used to describe how a set of actions are to be encoded onto a NFC tag or to be exchanged between two active NFC devices.
When working with NFC tags and Android-powered devices, the main format you use to read and write data on tags is NDEF. When a device scans a tag with NDEF data, Android provides support in parsing the message and delivering it in an NdefMessage when possible.NDEF Library for Arduino. Read and Write NDEF messages on NFC Tags with Arduino. NFC Data Exchange Format (NDEF) is a common data format that operates across all NFC devices, regardless of the underlying tag or device technology. This code works with the Adafruit NFC Shield, Seeed Studio NFC Shield v2.0 and the Seeed Studio NFC Shield.
The NFC Data Exchange Format (NDEF) is a standardized data format that can be used to exchange information between any compatible NFC device and another NFC device or tag. The data format consists of NDEF Messages and NDEF Records. The NFC Data Exchange Format (NDEF) specification defines a message encapsulation format to exchange information, e.g. between an NFC Forum Device and another NFC Forum Device or an NFC Forum Tag.
