NFC Tags NFC Stickers Waterproof Programmable NFC Cards and Tags 25mm Black N...

These NFC tags are flawless in performance, earning a well-deserved five-star rating. Whether it's for automating tasks, sharing information, or enhancing convenience, these tags deliver without a hitch. With their reliable functionality and ease of use, they are an excellent choice for anyone looking to harness the power of NFC technology.

You know what you want to buy this for. Just know, they work. They're pretty easy to lose in darker areas though, so keep them somewhere secure.

Not bad, they work. However, you cannot use these for proper security uses. You may be able to force less secure systems, but the signature doesn't seem to be from a registered manufacturer. The signature IDs are unique to each other (I assume, I ran 10 really quickly, all different signatures). I may try to associate them with one of my internal CAs if I can, but I am going to poke around a bit. Otherwise, they are as described. Each round tag is about 20mm, flat black both sides. You will have to package them for use, but that's pretty much a given with bulk tags. I got a package of 50 for general use with my workshop inventory system (which is larger than many commercial workshops, huge quantities of electronics components, parts, etc), and I will probably use them for various stuff around the house.

I added these to my business cards so that there would be a quick and easy way to get to my organization's linktree. It was at a tech-heavy conference/trade show and was a big hit! I had people asking me to show them my "business card trick." The size is perfect for a card that size, and the shiny black was a noticeable yet subtle pop on the black background. Ordered more so I can add it to all my business cards. My company was impressed with my "coded" cards. Don't get one of those "fancy" business cards that do this same thing. Just use your classic one and add this sticker. Sleek. Programable. Easy to use and fascinate others with.

Works as expected. Be aware that do not work with many Android phones. Works with all iPhones so far from. Do not stick with clubber like I did at the back of your iPhone or else it may not work as expected (I did that thinking I could put it close to other iPhones for networking purposes) but that didn’t work. The nfc needs to be close other phone so it works and has to be where your iPhone camera is located. Tips: make sure you add some stickers to your nfc so when networking it is easy to recognize which nfc tag is about.

Got them working in no time. Used the NFC Tools app on iOS (Apple). Also I used Dibiz.com to create my own business card. I can now insert the small chip on my phone case or in my case to share my contact info quickly while I'm at a trade show. I also ordered a Linq card, I'll compare and see how I like it. These are very easy though, took me only a few seconds to learn how to write to the chip from my app. Just search NFC write or something similar in the app store to find an app. Then google for business card or whatever you need online.

I buy these all the time and they are totally worth the money. You can reprogram them as many time as you want as well.

Very good tags but it is not a sticker there is no peal or anything sticky on any of my nfc tags, I don't know if it was just an issue with mine or not but I tried to peal it with a screwdriver, and still nothing.

Llego en el tiempo establecido y ha funcionando muy bien.

Good quality
