I wanted to have an easy way for guests to connect to the WiFi (and I have a very complex wifi password), so ... what better than this NFC card?Pro: it is a very thin card (it easily fit in your wallet, I'd say is even a hair thinner than a debit card, since there are no engraved numbers or other), it's really easy to put your own content, and - at the time of writing - it uses the latest NFC standard (888 bytes available, which can be password protected). As well, seller is very responsive and available, it just makes things easier.Neutral: print quality is very good, but there is a bit of color loss once printed (I have lost a bit of magenta on the print, only noticeable because I made the image from scratch with a gradient), but that might be the color space / monitor I used during creation. Be aware that the resolution in the front seems to be higher than the one in the back (lines are sharper in the front, meanwhile there is a bit of pixellation on the back). I used a fairly detailed background (for both sides), that's how I noticed the difference - but to be honest - you might not even realise. About the color fidelity, I'm not a designer (just a developer, that's why I know about color space), but I printed a few photos in the past, and I realised that they'll never look as they look on the screen, it depends on thousands different things, and it's just impossible to attain the image on the screen on the printing at first try.Cons: not really, it's really good value for the money! :)I have to say I'm very happy with the purchase, once guests will be allowed again I'll have something to show off! Thanks NFC tagify!
