'TapWise' NFC nTag 10 Pack

disclaimer: I haven't used these with an S4 yet just an S3, but they are supposed to work with the S4 and I will update this in 2 weeks when I get the S4__________Great looking tags, they don't have advertisements/websites on them. Just purely say NFC and have the tapwise logo (not that anyone recognizes their logo). Took a while to arrive...like 9 business days or something, but I wasn't in a rush.They write perfectly and read perfectly through a otterbox commuter case. They have low writable space so if you have the S4 (or a Nexus device??) and don't want to use NFC in conjunction with Tasker buy Topaz 512 tags which have a lot more space. If you plan on using tasker for your profiles and NFC tags merely as on/off switches then the low write space is not a big deal. If you have an different (older?) NFC phone, like the S3, buy the 1k tags sense they are compatible.These appear to stick well, but I have yet to actually put them anywhere because I'm waiting on my upgrade to S4 to start placing them (I will update this when I start using them actually).For the price I paid, these tags are probably the best out there.

If you're new to NFC and how it works, I'd highly recommend starting with these. They simply work, even with a thick case like an Otterbox on. Stick one on your nightstand and tap it before going to bed to set your alarm and silence calls. Or stick one in your car and tap it before you drive off to turn on your bluetooth and GPS and start playing music. Pretty much program these chips to do whatever you'd like. Just download a free app like NFC Task Launcher and your good to go. The only problem I encountered with these is that they won't work on a metal surface. I tried to stick one on my toolbox and it wouldn't pick it up. Otherwise I'd give it 5 stars

Attempted to write a couple of tasks to one of these it required just over 200 bytes. Came back with "only 137 Bytes" of memory available. Won't work for anything more than listing a web or email address. Useless for what I bought them for.There are Apps that will automate a limited number of tasks using these,about four or five, but, it will not work on someone else's device unless they are running the same App, same settings.

These are smaller than I thought they were. They're ever-so-slightly larger than a USA quarter. They work great with my Nokia Lumia 920 Windows Phone 8. I will be purchasing more.I affixed a tag to my  Rabbit Mini Portable Stand for iPhone 5, 4S, 4, 3Gs, iPod, Samsung Galaxy S3, S2, S Phone, HTC and other Smartphones  so I can launch a clock app to display while my phone charges at my desk.[Update 01/03]: I have replaced my Rabbit stand with a Nokia Wireless Charging Stand, which has a built-in NFC capability. I moved my sticker to the top of my  Creative D80 Wireless Bluetooth Speaker (Black)  so I can launch my Bluetooth settings and connect to the speaker.I also have the  GOgroove BlueGate Wireless A2DP Bluetooth Audio Music Receiver & Adapter for Portable Speakers , Headphones , Home and Car Stereo Systems  and a  Motorola T325 Bluetooth Portable Car Speaker (Black, Retail Packaging)  in my car, and if I don't turn them on in the right order, I have to adjust my Bluetooth settings. I put a sticker on my dash so I can tap the phone, approve the NFC-based program launch, and enable the appropriate device.

hmm.... haven't found much use for them. Only a "wifi" card. Having the Wifi information on one of the tags and sticking that to the back of a bicycle playing card. That way when people come over, and ask for the wifi password, i can just hand them the card and done.Still trying to find other creative ideas on what to use these for. But they are interesting, worth a try in my opinion.

Just bought this to test the nfc on my lumia 820. It has around 130 bytes of writable memory, which is fine for a Windows Phone. If you are using a WP, please note that you cannot program a tag to change your phone's settings. It can only open the respective settings page. ie if you write it for wifi, the wifi settings open and then you have to manually switch the wifi off/on. They say its a security feature to prevent public tags from stealing contents from your phone. Yeah, I was a little upset to hear that too. Also, I was not able to write multiple commands on one tag.The most useful tag I use is the one with my house address, which I have stuck on the dashboard of my car. Other than that I couldn't find much use for it.As far as the product goes, it does what it says. Timely shipping, nice product. I wouldn't spend money on the 1kb tags out there as 130b is more than enough for a Windows Phone.

Because there is only 144bytes of space on each tag, you can't even set the tag to turn on bluetooth for the Galaxy S3 which would take about 163bytes of space. Do a search for "NFC 1K" if you want to be able to do multiple things with one tap. Biggest waste of $10 I've ever made on Amazon.

I was looking around for some simple NFC tags so I could slowly immerse myself with this technology. These tags are well worth the buy, and seem to have a better payoff instead of the Samsung TecTiles (5 NFC chips for double??? No.)I am able to write data (using an application from the Google Play store) and read it just fine from my Galaxy S3.These tags are roughly the size of a U.S. quarter.Pros: You get MORE than for what you pay here from what I've seen. Nice design.Cons: The stickiness of these tags aren't very reliable. I do have one near my light switch on my wall and it's holding up fine, but other than wallpaper or wall paint, I'm not sure how these would hold up elsewhere.Overall - buy these tags if you want to first set up your new NFC lifestyle. These are excellent tags that get the job done. (Be sure to download FREE apps from the Play Store as well)
