Very good quality. I use an app on android called "NFC TOOLS". It takes me SECONDS to program an NFC chip and stick it anyplace, where I want people to scan it. Be aware that these specific NFC tags CANNOT be placed onto metallic surfaces. These are strictly meant for non-metal materials. I use plastic cards for the businesses my siblings have and they work great. If you're willing to put in 10 minutes of effort, you could easily achieve the same result as the "dot" card. I would much rather pay $10 and put in 10 minutes than waste $50-$100 and an hour for some crappy metal card. 10/10 have recommended to family and friends

The NFC tag recognition by my phone (iPhone 13pro) is very slow. Not sure if it's the tag's problem or my phone's problem, and it isn't very reliable. Sometimes it works, sometimes it doesn't. Also, the sticker doesn't stick to surfaces very well and falls off quite easily.
