From Wikipedia: Near field communication (NFC) is a set of standards for Smartphones and similar devices to establish radio communication with each other by touching them together or bringing them into close proximity, usually no more than a few centimeters. Present and anticipated applications include contactless transactions, data exchange, and simplified setup of more complex communications such as Wi-Fi. Communication is also possible between an NFC device and an unpowered NFC chip, called a "tag".
Since my S3 got NFC function built in, why not using it. First is to buy some NFC tags. Second, install the NFC Task Launcher app.
Got my NFC tags from taptap.my. The seller provides many useful tips to amateur like me. You can conveniently stick the tag to any location (thanks to the self adhesive tape). Be warned, there are few types of NFC tag (e.g. MiFare, NTAG203) in the market. Need to make sure your Smartphone supports it.
Once you got the NFC tag. You need to download the NFC Task Launcher (it's FREE) from Google Play. This app will allow you to program the assigned tasks on the tag. Don't worry, you can re-write the program on the tag as long as you don't create a read-only tag. You can even create a switch tag with dual actions, e.g. office and meeting profiles. Simply tap your Smartphone on the tag, you can switch the phone profile vice versa.
