Two of them I had stuck on something and decided to move them. As soon as I removed them from the surface, they stopped working. I guess once they are stuck on something, they can't be moved - even if you try to remove it gently.I had put another one in my wallet and after a couple days it stopped working as well. The last two tags I used I haven't moved and they appear to be working okay.It's a shame that these are not more durable... ### ⭐⭐⭐ Tags arrived unformatted, but worked after some effort *by D***S on Reviewed in the United States on May 18, 2014* I ordered these tags for my Lumia 1520, since they state that they are NDEF formatted and work with Windows Phone 8. When they arrived, I found I couldn't write to them at all. NFC Interactor stated that they may be unformatted, but I couldn't find any apps which could NDEF format the tags. I borrowed a friends Android phone which also stated that they were unformatted. I was able to find an Android app which could format them, at which point they worked perfectly on both phones. ### ⭐⭐⭐⭐⭐ Work Perfectly! *by X***X on Reviewed in the United States on July 18, 2014* They work as advertised, other than the range of operation, I have no complaints. I have the Samsung Galaxy S5, and if the NFC Tag isn't placed just perfectly, on a specific spot on the back of the phone, it will not activate. But that may be a phone/case issue and not the Tags. I use a magnetic dock in most cases where I use these, so it lines up perfectly each time anyway. It is also easily identifiable, so as long as you know where the reader is you will be fine. Oh and these things are thin; about 1/4 to a 1/3 the thickness of your average credit card. The Tags do not appear to be affected by a wireless charger or magnets near by; food for thought on your potential application.Further information about how I use the tags: I use Tasker and NFC - Tasker Launcher from the play store to activate a set Task. This way I can assigned each NFC Tag to a specific Task name (I named mine to identify their location; i.e. Car, Living room, Bedroom, etc), and just edit the task listed on my phone. This way I don't have to rewrite the NFC Tag every time I want to change what the Tag triggers. I can also make pretty complicated tasks (like executing different tasks at different times of the day/week for the same NFC Tag, or even checking to see if Bluetooth is connected before disabling, or even, after enabling Bluetooth, disabling it if it doesn't connect after a set period of time, or just about anything else you can imagine; Tasker is an awesome tool!). The possibilities are endless. For those of you who are familiar with Tasker, you know what I'm talking about. Everyone else, I recommend you give it a try.These things are awesome and work perfectly for just about any conceivable application. --- ## Why Shop on Desertcart? - 🛒 **Trusted by 1.3+ Million Shoppers** — Serving international shoppers since 2016 - 🌍 **Shop Globally** — Access 737+ million products across 21 categories - 💰 **No Hidden Fees** — All customs, duties, and taxes included in the price - 🔄 **15-Day Free Returns** — Hassle-free returns (30 days for PRO members) - 🔒 **Secure Payments** — Trusted payment options with buyer protection - ⭐ **TrustPilot Rated 4.5/5** — Based on 8,000+ happy customer reviews **Shop now:** [https://www.desertcart.jp/products/2574018-10-black-ntag203-nfc-tags-from-nfcguyz-use-with-galaxy](https://www.desertcart.jp/products/2574018-10-black-ntag203-nfc-tags-from-nfcguyz-use-with-galaxy) --- *Product available on Desertcart Japan* *Store origin: JP* *Last updated: 2026-05-13*
