what is an nfc sticker?

[OBLAMA2009]

i saw a couple weeks ago people talking about nfc stickers for galaxy s3 and now i just read a story about lg vu having stickers. why do you need stickers for nfc and does my verizon galaxy s3 need a sticker to do nfc and did it come with one???

Near field communication stickers are little NFC emitters in a way. If you turn NFC on and you have the NFC sticker near you (the sticker has to be programmed) and put your phone close enough, it will do what you programmed your sticker to do

Only if you want to create your own nfc situations. NFC works out of the box. S-Beam, Wallet, work without any further assistance.

NFC stickers are what the vendor needs. Your phone "scans" the sticker without needing anything else.

You can create your own nfc tags & make your phone do cool things, too, like turn on bluetooth when you get in your car, turn off data & turn on wifi when you enter your house.

No. For stickers ("tags") any tag will work fine.

You can use beam/wallet/check-ins without any stickers. Those are are device->device or device->wall-tag.

The NFC tags are used when you want to create your own NFC triggers. You program the tag to tell your phone to do something when scanned, and then can place the tag wherever. Then when you scan it, the phone does whatever its told. Could be as simple as "turn on wi-fi" or as complex as...well, almost anything since it can trigger a tasker task.

example, I have a tag in my car that turns wifi off, bluetooth on, connects to my stereo, adjusts the media volume, and then starts music playing. I have to pull out the phone, unlock it, and scan the tag, but thats easier than doing that sequence manually.

Huh, I didn't know that. I'm going to buy some then.

Anybody bought tags before? Where did you get them? There are links in the article above, just looking for more/better.

I got my tags from http://www.tagstand.com/

There was a booth showing it off. The presenter claimed it would be the end of business cards since you could use the tag to share your contact (assuming everyone has an sgs3 in the future)

Not true, as other members can attest: http://forums.anandtech.com/showthread.php?t=2248068&highlight=nfc

You do need to be careful which ones you buy as they aren't all compatible with all devices by default. It would be awesome if it was this easy, but sadly it's not.

NFC has been in phones for a while now... long before the SGS3. It's in my friggin credit card FFS.

The technology isn't new but do all phones that have NFC support using tags? From what I got from the presentation this usage was relatively new and one of the main selling points for the sgs3

Tags are not new at all. The Nexus S is almost two years old now and has supported that and I'm sure there's been other phones that have had NFC here as well. It's just been super slow to adopt here.

It's just because the SGS3 is the first "big" phone to have it. "Big" even outside tech circles.

op, NFC (near field communication) is just a revised technology of RFID (radio frequency identification). all it is, is a small microchip with a big (comparatively to the chip) antenna. when your phone or other nfc device trys to scan, the radio waves sent out are picked up by the nfc tag. part of these radio waves are harvested for electricity so the microchip can wake up and beam it's signal back out.

its pretty neat technology, but it still has a ways to go before its totally useful. thing is, its been in development for decades now and it might not ever catch on properly before something else replaces it
