30pc Black NFC Sticker Round (25mm/1in) NFC Tags Programming Compatible Android Devices

These work welland the adhesive is quite strong being able to be removed and still adhear to thingsImportant nfc tag note!!!They don't work if stuck to something conductive like metal!

I bought these for my mom, to keep track of oil changes, grocery list, alarms, kindle, canning. So easy, fast and amazing. Im going to buy these for myself. Easy to read.

New to NFC but impressed with the simple yet effective technology. You dont need a bunch of other equipment to read and write NFC because there are a bunch of iphone apps that are easy to use and learn. I was able to make a bio website with my business and social media information and stick it to one of my business cards. After programming the bio website link onto the NFC sticker, I tap the top left part of an Iphone and it shows up. It can take a few tries and sometimes it makes you feel dumb trying 5 times. Ive bought name brand, 20$ cards from other companies that make a big deal our of being able to tap someone your information and it also can takes 5 tries. Sometimes it happens on the first try and you look great :)

Worked as expected, great value

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 embed these in 3D prints, such as encoding purchase URLs in filament samples. They are .2mm high, so I just print a circle slightly larger, pause the print when it is about to print the layer above the hole, put the sticker in, and resume.I don't know how sturdy they would be if exposed, but embedded in the plastic I'm sure they will last indefinitely. Read range through the plastic is a few centimeters. Hard to beat for the price.

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.

I bought this product and it had a failure rate of near 100%. I tried multiple apps and phones to program them and I got one single tag to write but it won't read now after 5 mins and 3 scans its dead now. I tried every tag in this package and they all failed. What a waste of my time. Better off buying higher quality. I was totally SCAMMED.

I bought these stickers to replace the access cards that staff kept losing but wasn't sure if they would work. Thank goodness I took the chance! They work great and are easy to program. And it's more difficult for staff to lose them when they're stuck to their phone case!

It does exactly what was described. decent and I like it. Would purchase again in future if need more.

Fits easily into a loonie coin holder!

Pure connection, while sticks on the iPhone. Cannot transfer any information.

This product worked exactly how I expected. I will say sometimes I have a bit off difficulty having the phone read the tag, however, this can usually be fixed by readjusting the positioning of my phone. I've tried other brands, and so far this is my favourite.
