10 Black NTAG203 NFC Tags from NFCGuyz - Use with Galaxy S5 LG G3 & All Others

3 of my 5 tags have stopped working within a few days. Two of them I had stuck on something and decided to move them. As soon as I removed them from the surface, they stopped working. I guess once they are stuck on something, they can't be moved - even if you try to remove it gently.I had put another one in my wallet and after a couple days it stopped working as well. The last two tags I used I haven't moved and they appear to be working okay.It's a shame that these are not more durable...

I ordered these tags for my Lumia 1520, since they state that they are NDEF formatted and work with Windows Phone 8. When they arrived, I found I couldn't write to them at all. NFC Interactor stated that they may be unformatted, but I couldn't find any apps which could NDEF format the tags. I borrowed a friends Android phone which also stated that they were unformatted. I was able to find an Android app which could format them, at which point they worked perfectly on both phones.

They work as advertised, other than the range of operation, I have no complaints. I have the Samsung Galaxy S5, and if the NFC Tag isn't placed just perfectly, on a specific spot on the back of the phone, it will not activate. But that may be a phone/case issue and not the Tags. I use a magnetic dock in most cases where I use these, so it lines up perfectly each time anyway. It is also easily identifiable, so as long as you know where the reader is you will be fine. Oh and these things are thin; about 1/4 to a 1/3 the thickness of your average credit card. The Tags do not appear to be affected by a wireless charger or magnets near by; food for thought on your potential application.Further information about how I use the tags: I use Tasker and NFC - Tasker Launcher from the play store to activate a set Task. This way I can assigned each NFC Tag to a specific Task name (I named mine to identify their location; i.e. Car, Living room, Bedroom, etc), and just edit the task listed on my phone. This way I don't have to rewrite the NFC Tag every time I want to change what the Tag triggers. I can also make pretty complicated tasks (like executing different tasks at different times of the day/week for the same NFC Tag, or even checking to see if Bluetooth is connected before disabling, or even, after enabling Bluetooth, disabling it if it doesn't connect after a set period of time, or just about anything else you can imagine; Tasker is an awesome tool!). The possibilities are endless. For those of you who are familiar with Tasker, you know what I'm talking about. Everyone else, I recommend you give it a try.These things are awesome and work perfectly for just about any conceivable application.

I knew I should have bought the Samsung branded tiles, but I liked the wood tone for blending in with my desk. Unfortunately, every Profile I've tried to program with my Galaxy S6 comes back telling me that there is not enough space on the tile. Switching to the Car profile (turn off WiFi, Turn on Blue-tooth, adjust volume and brightness) needs 167, the tile only has 137. I'll be returning them and ordering the less attractive, but more likely to work, Samsung tiles.

These work, but the distance you need to have your phone at kind of sucks. Not a problem with the manufacturer, it's just a shortcoming of the radio in most smartphones. That being said, the quality of these tags is good, but I would use them unless you don't care about banging your phone on something.

This one of those items that I bought more as a curiosity to try them, and to learn something new.I have one label installed in the car phone cradle, I configured it to turn on the Bluetooth, turn on the GPS and Google maps, Google Music and it plays a greeting message when I place the phone on the car mount.It is a bit difficult to activate by hand or voice those 5 functions on my smartphone, while the phone is already in the cradle.I also installed one label on the icemaker dispenser in the refrigerator, if someone comes to visit at home, I just tell them to turn on their phones NFC, at to place the phone over the label, no more questions about a password, and the name of my network.Also to make it fun when their phones connect, I have a fun message for my guest that says they are connected to my network.You will need an app such as Tagstand, to program the NFC label, and of course a NFC enabled device.

These show up to my device (Nexus 5) as MiFare type tags and hence I can't write to them. Kind of a bummer. I thought NTAG203's were different, but guess not. I ordered some Topaz 512 and those seem to be the right kind.I'm giving it two stars because they say universal, but they're not... or I got the wrong item. I don't know, but it's frustrating.

There really wasn't anything wrong with this product, but by the time I had gotten I had less interest in using NFC tags, so I can't really rave about it. Shipped quickly, everything was in order. Just fine. A little expensive though.
