While it is possible to write multiple records to a single NFC tag, in order to keep the UI simple, AppSheet will only use the first record in the tag. When they do, the tag's value will be filled in the relevant text field. When your users click the NFC button they will be prompted to scan a tag. Since scanning NFC tags is possible only from mobile devices, the NFC button won't appear when accessing your app from a browser. Once enabled, an NFC button will appear next to the text field of that column when running the app on a mobile device. In the app editor, go to the definition of the column you would like to scan, and mark it as NFC scannable. You can write some part of data into your tag (typically an ID) and then use your app to read the value from the tag into a field in a form or the search bar.Įnabling data capture is very simple. The use of NFC in your AppSheet app falls into two categories: data capture and links Data capture While NFC has many capabilities and formats, AppSheet is currently supporting reading records from NDEF tags such as the NTAG215. This, combined with the affordable price of tags (from ~0.5 USD per piece), is making NFC an attractive feature for some app creators.Ī tag can be read by physically touching it with a NFC supported phone or device. Most modern smartphones are capable of writing to and reading from NFC tags. It's possible to change the default payment method, but not possible to disable it, although I'm not sure if that would help.Near Field Communication (NFC) is a short-range protocol of communication between devices, typically between an NFC tag and a scanner. I looked under Settings -> Connected devices -> Connection preferences -> NFC, and I see 'Contactless Payments' settings. Is there another app that runs permanently in the background? Then I let NFC ReTag write its details to the tag (a cheap NFC sticker), and now it works automatically, with no prompt from Android, but I would also like to trigger actions from read-only NFC tags. I gave NFC ReTag all the permissions it wants, but there seems to be nothing to make it the default/automatic app for NFC tags (unless it's currently running). I don't have an app called 'Tags' - it seems to be a built-in tag reader that doesn't do anything, and doesn't know much about it: Then I tried NFC ReTag, which seems to offer exactly what I want, and is easy to use.īut if the app isn't running, then Android asks me to 'Choose an action', with options 'NFC ReTag FREE' or 'Tags' (which says 'New tag collected'). So I gave up on those apps and deleted them. I can link the tag to Waze, and the NFC app remembers that, but nothing actually happens when I tap the tag, even when the app is running. I tried NFC Tools / NFC Tasks, but the app(s) just ask me to write data to a tag - my tag stickers are writable, but other cards are not. I don't want the phone to pop up a prompt asking me what to do - I just want the app to launch. I would like to launch an app or run an action automatically when I tap my phone to a tag.įor example, if I get in my car and tap a tag on my dashboard, I would like Waze to open. I have an NFC-capable phone (Nokia G60, Android 12) and a bunch of NFC tags/cards.
