Kamor 10 Ntag216 NFC Tags for NFC Enabled Phones Bundle with NFC Key-chain and 12 Stickers

Fantastic product and specifications.The tags are high quality hard pieces, looking cool enough so I did not care about using the stickers.And regarding NTAG216 I did not really have idea that it would be able to carry so much information within, I did select this specific one to have the latest... and WOW, my longest info+command takes just 1/3 of its capacity, what means my own creativity is my limitation now and not the tag's memory. Being just a bit more expensive than others, I would say it definitely worth having this one and avoid being concerned of how much of its memory you are using, its capacity is really surprising!I have been using with my Moto Maxx (aka Droid Turbo) and also tested with couple more devices, working like a charm!

Updated review: I added a star for exemplary customer service. After reading my original review, they sent me a refund, with their apologies for any inconvenience their product caused me.They're bit thicker than other NFC tags. The 3M adhesive is incredibly tacky. It's nearly impossible to remove the tag once adhered in place. They seem to work just fine, but not with a Galaxy Note 4. It's not necessarily the tag. It's probably the phone. I've tried several different tags and none of them seem to work properly. They work great if you simply want to tap your phone to it, you'll have to hold contact for a couple of seconds before tag is recognized. If you want to place and leave your phone on the tag, on the other hand, the phone keeps trying to read the tag. Often with an "empty tag" error message. This is true with a protective case and without. Again, this is probably a phone issue not a problem with the tags.

I never order this.

Pretty much a waste of money, they don't work with the phone locked unless you have a custom rom... pointless tech.

I lost them.

I gave these a 5 star review because they work with no issues. I've been using them for over 6 months now with a Samsung Galaxy S5 with no problems with an app called "Trigger". There are many apps available, most for free with paid features - but this one is pretty easy to use and has the ability to use a tag to switch between two states.You can use the tag with any NFC capable android phone - here's some ideas of ways I use them:In the car: Tap once: turn off wifi, turn volume up, turn on bluetooth, connect to bluetooth adapter, start playing spotify - tap again to turn volume to vibrate, turn off bluetooth, turn off spotify.on my nightstand: Tap once: Turn off notifications, Turn on wifi (in case it wasn't on already), silence phone, turn down screen brightness, turn off blinky notification lights - tap again: turn on notifications, volume max, brightness auto, notification lights back on.Stickers are kind of dumb to me - Most of my tags are obvious by context without the need for a label.

They shorted me one tag. Otherwise pretty happy with them.Work with my Note 4 and Trigger app.I use one in my truck to turn off wifi, open play music, and turn up the volume. Then it toggles when I get home to turn wifi back on.***UPDATE***The seller contacted me about the missing tag. Got a partial refund. 5 stars to YoSpace for customer service.I've upgraded the review here to 5 stars because the tags worked well, even though I'm only using one right now. It's behind the plastic cover in my truck's headliner that holds the overhead light in the attached picture. I slid it in there to hide it from view. It sometimes takes a few tries to get it to run. I do have a spigen casehttps://www.amazon.com/gp/product/B00MAWQN70/ref=cm_cr_ryp_prd_ttl_sol_10 on my phone that might degrade the signal, but I think it may just be tricky to hit the exact spot where I've hidden the tag.I've used the "free" one that comes with the little string for attaching to a key chain. I've since realized that I didn't need it to do the task I had it programmed for because Trigger would run the same task when I connected to my car's bluetooth. Trigger gets 5 stars too.I think I will program another one to connect to my wifi and put it next to my garage door.

I'm still wondering why I purchased this. The vender included some tips on how to use it. I'm well under the learning curve. Check back in a couple of months and see where I am. If I am still trying in a couple of months. Or if you are techno savvy, tell me some ways I can use it.
