Reddit reviews 8 Black NFC Stickers NTAG213 by Tagstand - Fully programmable, and Works with Android, Samsung Galaxy S7, S6, S5, S4, S3, Nexus 5, HTC, and All Other NFC Enabled Devices

i use it with NFC stickers around the house, paired with Trigger I can do all sorts of automation:

• lay my phone down next to the lamp to start playing music and turn on wifi.
  
• slap my phone against the wall as I leave the house to turn off wifi and enable bluetooth (for the car).
  
• put it on the counter to enable tethering.
  
• etc.

Out of the box the 6P has a saturated screen color. If you prefer a more natural color turn on Developer Options and go to:

Settings > Developer Options > Picture Color Mode

and turn on Use sRGB.

You have a multi-colored notification light at the top left of the phone. To make it display in different colors you'll need an app. I like Light Manager.

Your finger print scanner is going to be your new bestie. many apps that require logins now support the scanner. Lastpass and a ton of banking apps come to mind.

NFC works well (though you need to remember it's located right at the top in the visor on the back. I use a bunch of little NFC tags and NFC Tools to have the phone open Android Auto in my car and to open a shopping list when I tap it against one of my cupboards in the kitchen.

Something like NFC Stickers?

You can buy NFC stickers like this for real cheap

NFC stands for Near Field Communication. If you've ever used a badge or a keyfob for door access or used ApplePay you've used NFC. This release opens up NFC for jailbreak users and we can read/write NFC data via the NFC chip in iPhones.
Also the wikipedia entry for NFC has a pretty good video.

Lastly famous usages for NFC are:

• Nintendo Amiibo figures
  
  
• Some fitness machines (my personal fitness has them, from TechnoGym)
  
  
• Wireless paying. This includes both Apple Pay and its knockoffs (google pay, samsung pay etc) but also wireless paying with bank card. The latter is, last I heard, not very common in Murica but over here in The Netherlands it is super super common and stores even want you to use it in favor of your own security.
  
  
• Adding WiFi networks (instead of typing the security pass). Some routers support this
  
  And here and here are some more examples. NFC is a really awesome technology because it's super easy to use, tags are really cheap (8 for 10 bucks on amazon) and these kind of tags can hold all kinds of data from web addresses to share to the aforementioned data of Nintendo Amiibo figures if you can find their decryption keys (they are uhm.. "available" on the internet if you know what I mean)

Programmable NFC Stickers like these:

Ah shit my link didn’t work.

Probably because it had the share stuff in it. My bad, I’ll go back and edit

It is actually very easy to set up. The sleep app for android has the function built in (not sure if it's available for iphone). You need a phone with Near Field Communication (NFC) capability. Any cheap RFID tag should work, I picked up these ones from Amazon. You only need one, but they pretty much all come in packs. In the app settings you go to "CAPTCHA" and select "NFC tag". Then in the CAPTCHA settings there is a giant button at the bottom of the screen that says "Learn". All you have to do is turn on your phone's NFC and set your phone on top of the tag you want to use. Once it learns that tag, put the tag where you want it, set your alarm to not turn off without CAPTCHA enabled and you should be all set.

Yup. You can buy essentially blank but unique NFC tags and then use various apps to program the actions taken when they're scanned.

Here are some tags off amazon (there are many, just search nfc):

Doing a quick google search I found this guide about what you can do (although I didn't take a careful look at it):

https://www.amazon.co.uk/dp/B00KSR0636/ref=cm_sw_r_tw_dp_U_x_MpdNAbF8M1NF0

is what I bought - works fine with my Galaxy S6 to trigger Tasker tasks.

Also use the Android tools NFC Tools and Trigger (Trigger itself can call a Tasker event).

You can buy them from Amazon, and you can download NFC apps from the Play store to help you program them. Easy peasy.

Just pick up some NFC tags off Amazon (such as https://www.amazon.com/Black-NFC-Stickers-NTAG213-Tagstand/dp/B00KSR0636)

Then set up a trigger once you scan to connect to the specified WiFi and input the set password. Of course, they'll need to have NFC enabled, not everyone does or even knew it existed on their phone.

Are these different? Like better or worse or something?

Programmable NFC stickers, combined with apps like Tasker allow you to automate various settings based on a NFC swipe. I've used one in my car as well to turn on Bluetooth, start Spotify, crank volume for audio and alerts, switch GPS to high

How thick are they? smallest I've found are ~ 1mm these
