This document describes the basic NFC tasks you perform in Android. Reading NDEF data from an NFC tag is handled with the tag dispatch systemwhich analyzes discovered NFC tags, appropriately categorizes the data, and starts an application that is interested in the categorized data. An application that wants to handle the scanned NFC tag can declare an intent filter and request to handle the data. This interaction provides an easier way to send data than other wireless technologies like Bluetooth, because with NFC, no manual device discovery or pairing is required.
The connection is automatically started when two devices come into range.
For example, the Contacts, Browser, and YouTube applications use Android Beam to share contacts, web pages, and videos with other devices. Android-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 Android-powered device discovers an NFC tag, the desired behavior is to have the most appropriate activity handle the intent without asking the user what application to use.
Because devices scan NFC tags at a very short range, it is likely that making users manually select an activity would force them to move the device away from the tag and break the connection. You should develop your activity to only handle the NFC tags that your activity cares about to prevent the Activity Chooser from appearing. To help you with this goal, Android provides a special tag dispatch system that analyzes scanned NFC tags, parses them, and tries to locate applications that are interested in the scanned data.
It does this by:. Before you begin writing your NFC applications, it is important to understand the different types of NFC tags, how the tag dispatch system parses NFC tags, and the special work that the tag dispatch system does when it detects an NDEF message. NFC tags come in a wide array of technologies and can also have data written to them in many different ways.
Each NDEF record must be well-formed according to the specification of the type of record that you want to create. Android also supports other types of tags that do not contain NDEF data, which you can work with by using the classes in the android. To learn more about these technologies, see the Advanced NFC topic.
Working with these other types of tags involves writing your own protocol stack to communicate with the tags, so we recommend using NDEF when possible for ease of development and maximum support for Android-powered devices. Valid values are described in Table 1. Variable length type Describes the type of the record.
Valid RTD values are described in Table 2. Variable length ID A unique identifier for the record. This field is not used often, but if you need to uniquely identify a tag, you can create an ID for it. Variable length payload The actual data payload that you want to read or write. However, there are cases when the tag dispatch system cannot determine the type of data based on the first NDEF record.

For that reason it comes with fully featured SDK package, which includes firmware, libraries, software examples and documentation for various platforms, operating systems and developing environments.
All mentioned facts combined with free extensive and fast responsive support give this product an outstanding position in this industry sector. It utilizes an outstanding modulation and demodulation concept completely integrated for different kinds of contactless communication methods and protocols at Reader has built-in anti-collision mechanism for detecting multiple cards at time.
Communication with host is provided by using USB 2. Data transfer rates are limited from baud to 1 Mbaud, for integrity and security reasons. Audible speaker and 2 LEDs visible indicators are built in and absolutely user controllable. Since hardware is based on MCU platform, it runs on company developed custom firmware.
Communication between host and reader is provided through high speed direct access FTDI chip features. At core communication level device uses company developed, proprietary communication protocol, which is well documented in SDK API reference. Main point about firmware is that all firmware functions can be called via communication protocol, too. That fact moves usage of this device into other dimension, meaning that this reader can be used on almost any platform which has serial interface, by simply using communication protocol.
Firmware is regularly updated with new versions which include new features, improvements and bug-fixes, while preserving backward compatibility with older versions. That means your code is safe, there is no need for changes when new firmware comes out. Reader comes with fully featured SDK which consist of external libraries, software examples with source codes, documentation about API reference and communication protocol and some useful software tools.
Other platforms can be supported as custom release, on customers demand, depending on existence of project or partnership relation.
Software examples are divided in three stages according to complexity, with some new additions of NFC examples. Other programming languages examples can be obtained on customer demand,depending on existence of project or partnership relation.
However, API is much more comfortable and recommended way of implementation. Where not possible, implementation of communication protocol is very good alternative, especially when using RS model. All libraries, software examples, tools and documents are regularly updated. Our support team always provides quick response, usually not more than 24 hours, which also depends of complexity and question itself. We can also provide custom solutions based on each customer's needs, so please free to contact us for any question or further help regarding your projects and implementation.
Depending on antenna geometry and reader configuration, operating distance is cm 0,78"-3,15". USB 2. However, serial protocol must be implemented separately and is not part of SDK. More Info Allow Cookies.

Simple NFC android code to read the tag.I wanted to create an attendance capturing system using NFC tags. I was unable to find a decent document on the internet to resolve my issues. So I did researches my own and was able to achieve what I wanted. This document contains what I have done, and thought to share with you if you are struggling to get started with NFC readers.
I programmed with C language with WPF interfaces and winscard. In this article, I'm trying to show how the application would communicate with the reader and card in order to identify the card's UID. The card's chip contains a unique serial number for identification purposes, this is called UID. So we can identify tag from each other. First of all, we have to create the following class on our solution to include all our NFC card related functions.
See below code establishContext ; MainWindow. Here is rest of the main window code: That is all you have to do.
Stack Overflow for Teams is a private, secure spot for you and your coworkers to find and share information. This is a contactless smart card reader. This is because, I have purchased the NFC card reader but without the software. So if there is any other tools that can actually reads the ACRU, other than the original sdk itself, do let me know.
