NFC: Near Field Communication

NFC products available since 2005

First NFC Phone - Nokia 3220 NFC

NFC is a type of RFID.
RFID tech is being used increasingly for identification & financial transactions.
As keys to open locks of all kinds.
As the mobile phone has become a “convergence” device for other portable electronics,
so too it may become a universal “keyring” for RFID applications

Android NFC Development











NFC Basics
This document describes how Android handles discovered NFC tags and how it notifies applications of data that is relevant to the application. It also goes over how to work with the NDEF data in your applications and gives an overview of the framework APIs that support the basic NFC feature set of Android.
Advanced NFC
This document goes over the APIs that enable use of the various tag technologies that Android supports. When you are not working with NDEF data, or when you are working with NDEF data that Android cannot fully understand, you have to manually read or write to the tag in raw bytes using your own protocol stack. In these cases, Android provides support to detect certain tag technologies and to open communication with the tag using your own protocol stack.

NFC Basics

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.
There are two major uses cases when working with NDEF data and Android:
  • Reading NDEF data from an NFC tag
  • Beaming NDEF messages from one device to another with Android Beam™
Reading NDEF data from an NFC tag is handled with the tag dispatch system, which 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.
The Android Beam™ feature allows a device to push an NDEF message onto another device by physically tapping the devices together. 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. Android Beam is available through a set of NFC APIs, so any application can transmit information between devices. For example, the Contacts, Browser, and YouTube applications use Android Beam to share contacts, web pages, and videos with other devices.

  5. A printer driver is a PC program than empowers programming to speak with a printer. Each brand of printer has explicit programming that it used, in view of its working system, that changes information over to be printed to a structure explicit to the printer.

    In the event that printer drivers are obsolete, your printer probably won't function as expected until How to Download Printer Driver and introduce the latest update.

    Instructions to refresh printer drivers

    The technique for refreshing your printer drivers will rely upon the working system you have, so the best thing to do is actually look at your manual or the printer producer's site.

    Windows 10

    2. Snap on 'Equipment and Sound'

    3. Snap on 'devices Manager' to show all of the associated equipment on your machine – search for the 'Printers' drop-down which will contain any pertinent printers

    4. Right snap the printer you need to refresh the drivers on and click 'Update driver'

    5. Pick whether to look for drivers consequently or physically – pick naturally except if you have effectively downloaded the most recent drivers or have them on outside capacity
