Buy your tags at
tagstand - Buy NFC tags, labels, and stickers here..
I bought these:
tagstand - Logo Type 2 NFC Sticker - Ultralight C - Square (35mm x 35mm)
Make sure you check the box for - $1.20 USD -
NDEF Formatted
I bought 6 of them but have only found the use for 1 so far - in my car mount.
Then buy NFC Task Launcher:

It's very easy to set up using that app. You choose your criteria and save. Once you save, it will ask you to tap the phone to the NFC tag to program it. Once programmed, you are good to go.
The only gripe I have is the space on the tag is rather limited - so you can't ask it to do EVERYTHING. I think the solution is integrating it with Tasker but I haven't gotten that far (ie, tap the tag and load a 'task' - which has unlimited potential).
