NFC tag scan on iPhone is (almost) useless
- PaulHoule 5y agoMy beefs: (1) The iPad has an NFC terminal but is locked down so it can only be used for payments (2) NFC competes with QR codes for many applications. iOS support for QR codes is great because it is built into the camera app so you can give simple instructions for how to read the codes. On Android you usually have to download a third-party app. Usually I have to try two or three before I find one that really works and doesn't crash. I don't know how to educate Android users to be able to read my codes. (3) There is no standard logo for NFC, the one used for credit card contactless payments looks pretty good and I think people recognize it but you need permission to use it. You have to hold your device close to the NFC and that is a problem for an application like this https://gen5.info/$/XQ*42RXF-TLY:$B.8/ https://gen5.info/$/XQ*42RXF-TLY:$B.8/ where I have about 40 cards stuck to the wall with blu-tack. All of them have a QR code (which you can't read when it is stuck to the wall) and many of them have an NFC. The NFC really has to go in the same place for all of them so I can find them, but that contrasts with my desire to position the QR codes some place that minimizes how visible the QR code is when the card is held in hand and light passes through it. The effective answer is that there is a placard on the wall next to that grid where you can see all the cards in the constellation, but at 16 cents a tag an imperfect NFC that nobody will scan is hard to justify for an 8x8 card that has a materials cost around 25 cents.
