20pcs NFC Tags 215 Ntag215 Blank Cards - 504 Bytes Programmable, Compatible With NFC-Enabled Mobile Phones & Devices, Including iPhone

As far as these go, they work great. It's tricky using ncf tools to figuer out how to put data on them, but they do exactly what they say. This issue is, not with these cards, but with IOS/Iphone. Apple won't let you load them to send contact info. You can only use them to send as a direct link to your website or social media pages. You can enter all your personal information, contact phone number, etc. It won't matter since nothing shows up except you website or socia media. For that purpose, they are fantastic

I've bought 120 of these so far. A pack of 50 last year and a pack of 20 + a pack of 50 a few days ago. And only 1 card out of those 120 appear to be non-functioning. My guess is that the chip didn't get added during manufacturing, the chip broke during transit, or I messed it up here at home. Either way, 1 bad and 119 good is a REALLY good rate! I 100% recommend these!

They arrived well packaged and worked as decribed. No issues at all with programming them, erasing them, or anything.

Those in the legally grey trade of Amiibo spoofing should rejoice. At a little over a dollar per tag, all you need is an Android phone, TagMo, and some code off Github to do anything from adding your favorite villagers to Animal Crossing to loading a character save in Breath of the Wild.The cards are as sturdy as a bank card, and can be marked with most inks. They write and load quickly. I've yet to have one fail.These are also useful for a smart ID at conventions, such as linking to a Carrd, resume, or professional portfolio. It can represent attendees far better than a nametag!

The cards work fine and are reasonable sturdy. The only reason it's not a five star overall is one card out of twenty was bad. That tends to happen, especially with electronically sensitive materials so I feel like only one bad was about right. Plus, as there's no way of knowing if the malfunction on the card was their end, my end, or anywhere in between, so I'm not holding it against them.

I purchased these cards to take advantage of the NFC scripting capabilities of my iPhone using IOS Shortcuts. The cards worked great right out of the box. From windows shortcuts you just add a new shortcut, select NFC automation and assign one of the many tasks and scripting options available. I use the cards for a bunch of different tasks like selecting my favorite radio station, calling a family member, and interacting with home automation to turn on or off wireless plugs.Automation makes tasks easy. I just hover my phone over the NFC Card and the ios shortcut runs immediatley. I'm afraid I'm going to need more cards.

While it does have some trouble tapping sometimes it works as well as any other similar product for a fraction of the price. The material is sturdy from what I can tell and is as described.

They are a bit pricey for just NFC cards but honestly they worked really nicely. I used them to make custom Amiibo and they work really well. They scan easily, they were easily written on and in some of the other reviews I saw that some said that two cards didn’t work for them but all of them have worked for me. I’m glad I ordered these even if they are a bit expensive for NFC cards.
