Only Pebble can do this? Apple Watch does that too, like literally I use mine for the same cases you described
- john-radio 4y agoApple Watch is arguably not a general purpose "smartwatch" since it's actually only usable by those who happen to use iPhones.
- Jackim 4y agoI think the above posted was saying more that the Pebble is the only smartwatch with all of those features.
- jonas-w 4y agoI don't get it, many smartphones and smartwatches can be read by Barcode scanners never had any problems with it. (I used a few different samsung phones and watches)
- diego_moita 4y agoDon't know about the Apple Watch, I'm out of Apple's walled garden. My experience with bright screens is that low density bar codes work ok mostly. But some high density codes don't work well. One of them is Plessey, still used in Europe.
- WorldMaker 4y agoApple Watch's OLED seems great with even the densest QR code profiles. (I have an older Series 5, I think, and have never had a problem scanning a QR code from the watch.) I think Apple tests it heavily, too, because a lot of the codes on "Apple Wallet cards" for things like a store's rewards program get scanned as QR codes, and at least several of those are extremely dense. (I haven't done the debugging myself, but I believe I read on HN elsewhere that at least one was just stuffing a full bloated JWT into a QR to explain its extreme density.)
