100pcs NFC Stickers NFC Tags Sticker NTAG215 Black NFC Stickers Round (25mm) RFID Sticker, Blank NFC Tag 504 Bytes Programmable NFC Tag Sticker,Compatible with Tagmo and NFC Enabled Phones Devices

Lot of fun to mess around with! The NFC tool you can download for free on your phone makes it super easy and enjoyable to program these stickers. I got creative and used one on the baby’s formula, so when I pressed my phone to it, it would automatically log that I made a bottle and what time. It was such a great way to keep track of feedings effortlessly. These tags are a fantastic, versatile tool that adds a cool tech twist to everyday tasks

Works great. Stickers are the size of a US quarter and work as intended. Great for tagging NFC's on anything you can add a sticker to. Range isn't crazy (it's a sticker) but doesn't require touching to read the NFC like some other NFC stickers and doesn't stick out. You can re-write, add tasks/automation/etc.. Originally item was missed in my order and Customer Service was very helpful. Will likely be buying more.

The product is excellent so far - I wanted an alternative to business cards, and having one of these 'stickers' on my phone case pointing to my LinkedIn profile is a great option for that. Another great use is to share your home wifi connection with guests (I stuck one of these on my porch for that purpose). However, these came with no instructions whatsoever. What worked well for me eventually is the "NFC tools" app, so just sharing this in case it helps others. I did not rank the sturdiness (yet), because I just got these, we'll see how they fare over time.

I am not only shocked with how far are technology has come I’m shocked with how much access we have with it. These little stickers can be recoded almost infinitely. Not only do they have a decent amount of storage there also compatible with your phone through several different apps. These are cheap easy to use and create a lot of traffic. You can put em on just about anything even your phone or phone case. I’ve used them for menus at restaurants ways to leave a review and more.

Purchased these for a project I had in mind where anyone with any NFC capable device could read these tags. Yes, they do work with iPhone and will hit every single time, you just have to limit the data. Short text or a URL will be read immediately by an iPhone. Anything beyond that and it's a no-go. If you are writing code that needs the tag trigger, keep the string as short and clean as possible or you will be fooled into thinking these tags are faulty. You can literally max out the full 490+bytes and an Android will pick up all of it every single time. Keep this in mind before purchasing. I was unable to write with NFC Tools using an iOS device, maybe the full 490+bytes would be accessible to iPhones then.

I stuck one of these programmed with the network credentials to the back of an Acrylic Wifi Password Sign from ONLYKXY here on Amazon and wrote "scan me" on the write in boxes for name and password. Works great.

They read just fine, but a error pops up if you go to write to them (these are not 0x04 compatible). All tags I scanned had the same issue, which means these are not true NFC writable tags

First of all I'm a photographer and my job requires that I'm always networking at events, so I have two of this stickers on my camera, one on my flash and the other one on the hood, one sticker has my business card information and the other one the web gallery of that specific event, which I programmed using NFT tools, super easy.Since I have the camera with me most of the time when someone asks for my biz card i just tell them to tap their phone on the sticker and voila, I'm using the free linqapp profile which can give you a profile url that you can write on the nft tags.
