5 Black NTAG203 NFC Tags from NFCGuyz…

Worked out well, however I would have gone with more storage on a NFC tag next time, as I am running out of space to program onto.

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.

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...

There is not much to say about this except that it works as advertised. The tags are black and look better than the gaudy colored ones that everyone else sells. They are also exactly flat which makes them fit on things better. Tested on: Nexus 5

My phone doesn't recognize the NFC tags. Also, the price is way too high for what you're getting. I bought them, so the joke is on me, amiright?

Programmed with trigger and Nexus 5. Not sure if my phone had problems, but didnt work as well as I expected. Had to run my phone for 10 seconds or so against before Tasker tasks were initiated with NFC Tag

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.

Ordered the 10 pack and had 3 dead on arrival .. The other 7 worked fine and seemed to be compatible with the 3 phones I tried em on .. 3 stars for only getting 70% of what I payed for
