Nfc tags for dummies (I'm the dummy)

[TulpiX]

I understand the security concerns. But i would prefer the checks for unlock to be in the aplication rather than system wide.

Something like apps could register to nfc tag scanning while locked and others not. So you could use automatisation while locked and apps like google wallet would not work.

Just thought I would post here to give the guys at www.nfcdog.com some kudos. I ordered a few of the 1K NFC stickers to play with my Nexus. I noted that my order was #100 and cheekily asked if I had won a prize.

They have thrown in a free anti-metal tag too

Nice easy order process via Paypal too. I look forward to messing with them

Alright, now i feel like a dummy working with NFC Task Launcher. When i open the app all i see is a set preferences below window. I can't do anything else with the program. I don't see an OK button, or any way to get out of the set preferences below window... Am I missing something?

edit: Nevermind.. seems you need the pay version to create anything useful...

You also got another 25mm tag

Thanks for the kudos, we're learning as we're going!

I ordered pre-formatted tags from Amazon, that was very easy: http://amzn.to/xtnnAP

When you guys say that with < 4.0.3 we have to buy pre-formatted tags, what do you mean? We have to ask the store to prepare the tags to do the tasks we want? Or just format them in the NDEF format and then we can write the tasks with 4.0.1 or 4.0.2? Or am I just saying crap?

I wasn't able to understand this, need some clarity here... I need to know if I can order some now or wait until I get 4.0.3..

Thanks

We also sell formatted tags on Amazon's UK site under nfc-supplies (ebay as well) and tappitag. nfcdog.com is a little cheaper though

It just means they have to come already formatted with ANY NDEF message. It doesn't matter what it is. Once it's NDEF Android can use write from the NDEF library without a problem to overwrite the contents.

The issue is that the NdefFormatable tech isn't showing up for BLANK tags so they cannot be formatted NDEF (from non-NDEF).

Ok so I'll be good to write my tasks with NFC Task Launcher in a NFC tag NDEF formatted, with Android 4.0.2, right? I thought I wouldn't be able to write the tasks I wanted to perform... thanks!

Got the tags last night, awesome! They work with no problem and are so tiny!

FYI I am on GSM Galaxy Nexus 4.0.2

I bought the app discussed in another thread from the market to do all the profile changes etc. Works like a charm.

Oh, and thanks for the free tag and honest statement about postage nfc-supplies!

I wrote a quick blog post on setting those up. I did it for fun mostly but I find it a great use of technology to make your phone more usable in general:

Shutting off Bluetooth & Wi-fi this way also happens to save battery as I don't have them running for no reason.

Nice but not as useful as expected

Just got my tags today (ordered from TagAge, delivered in 5 days, got a Starter Kit, highly recommended for europeans). Using NFC Task Launcher and Tasker. After playing for several hours with it my conclusion is that it's more a "new toy syndrome" than a useful thing and here's why:
- NFC actions are one time actions; i.e. you touch the tag, the phone performs an action; there's no "exit task" (it's not like the phone is monitoring if it's still close to the tag), you have to touch the tag a second time to toggle a switch or touch another tag to perform a different task.
- ICS does not allow apps to turn on/off GPS so you can't use NFC for that (I was planning to enable GPS when the phone is in it's car holder)
- there's a beep every time you touch a tag; when you're in a quiet environment (e.g. bedroom) it's annoying; I haven't found a way to change the tone or silence it
- tags are pretty small, the largest I got could hold 1K. I tried putting a contact on it but it wouldn't fit, it was > 5 times bigger (photo?!). Other complex tasks can also get pretty big, bigger that can fit on smaller tags (most of them are 64 or 128 bytes). The workaround is to use Tasker: you create a Task that holds all the actions and use NFC Task Launcher only to read the tag and launch the Task. In this case using NFC is just ... geeky, you could do the same by putting a shortcut on your screen.

I just hope someone comes up with a much more powerful app, I feel there's more potential to be unleashed.
