😢you just don’t know how much you made my night with this valuable information. You are the GOAT

[@SudoScientific]

Aww, thanks! I appreciate you! -D

[@todd.westra]

I had no idea NFC tags could be so versatile! Thanks for explaining how they work. This opens up so many possibilities!

[@SudoScientific]

Of course. Thanks for watching! -D

[@hygorjardim2020]

Lots of good information here! I was just looking for security with NFC. It would be interesting (if possible) to add this label to the video where you explain how to set a password.

[@SudoScientific]

Good idea! I just added another video chapter label for the part where I set a password. Hope this helps! -D

How can the recipient have the option to save my information once I tap my card on his or her device?

[@SudoScientific]

If you link the card to a website (like shown in the video), then the recipient can just bookmark the website and copy the information down later. Or, on certain websites (dot.cards), there is an automatic save contact info feature. You can also directly write contact info into an NFC tag as an NDEF contact record, which a few NFC writing apps have, and the recipient should be able to save that info. Hope that helps! -D

[@abdollahzare5257]

If we prepare this card for another person, how can that person change his information?

[@SudoScientific]

That person should be able to wipe the NFC tag using "Format memory" in the "Other" section of NFC Tools, and add their new information using the same steps in this video. Hope this helps! -D

[@abdollahzare5257]

@@SudoScientific Can't edit your information online without using the application? Because some service providers of this card send a link to the email and the person can edit his information

[@SudoScientific]

I think you should be able to edit your information through that link on any online browser, without using an app. Tell me if this helps! -D

I got nfc ntag216 888kb storage, unfortunately it's not working on iPhone I used nxp writer to write url in samsung galaxy s21 fe it's working fine on it but on its not iPhone working I tired 7, 12 and 14 pro. Plz help. Should I return the tag, or is there a way to make them work.

[@SudoScientific]

NTAG 216s should be able to work…if you only need to write to your NFC tags once, maybe just using your Samsung Galaxy could work? Or if you want it to work on iPhones, you can try using a different app, such as NFC Tools on iPhones (although this is a paid app). Let me know if any of those solutions work out! -D

[@johnnytest9575]

​@@SudoScientific Bro, I tried but I think there was some problem with them, about being ndef, so returned it and bought a ntag215 from Amazon and they are working fine. I have written two links to the new cards 1 from of the unitlink profile and the other from the Canva project which contains my original card design and it works like a charm. Thank you for the reply.

[@SudoScientific]

That's great to hear! Happy to help! -D

[@jannet1017]

How I can print the cards, or add a design on the cards? thanks

[@SudoScientific]

Good question! There are a few options. (1) You can buy inkjet printable NFC cards (from Amazon or other places) if you have a compatible inkjet printer with card holding tray. (2) You can use a plotter with a Sharpie to draw your design. I used a Silhouette cutting machine with a pen holder (similar to a plotter) to write on the black NFC card in the video with a gel pen. (3) You can also use a laser engraver to burn your design on a light color card. -D

[@jannet1017]

Thank you, I have a inkjet printer and I have a plotter too@@SudoScientific

[@AsokeJasu]

Is this good for Google reviews?

[@SudoScientific]

If I'm understanding your question correctly, yes, you can have your NFC tag direct to almost any link, including a reviews page! If you meant to ask something else, feel free to clarify, and I'll get back to you! -D

[@engmuhammadzubairmalik1568]

@@SudoScientific I second, it is possible for reviews and even more attractive to customers
