Waveshare 1.54inch NFC-Powered e-Paper No Battery Wireless Powering and Data Transfer (Pure White Case)

It does the job and it's reasonably priced.

Lovely device, lots of fun and images look better than I expected. Would be better if the app to use it was in the App Store rather than a download from a website.

Does not work as described! Stuck at update

**Ignore the badly cut screen protector I put on the device - it's not a device flaw!** So cute and fun! I love it. Let me help you love it too by sharing some 'how to' info. I use this with an older Samsung phone. It did not come with any keyring or chains, so be sure to have a small ring to loop through it! - If you use an iPhone, you download the app from the app store, it's called "NFC E-Tag" there. If you use an android phone, you download the app as an installable apk file from the instructions page mentioned below. (Why they don't have the app on Google play, I don't know. I installed on an old phone so I don't have to worry.) - Find instructions and the app by looking up "1.54inch NFC-Powered e-Paper (BB) wiki" (IGNORE it saying 'not compatible with android Samsung Google phones', that's not true! I'm using a Samsung with it, I think the text was just written or translated wrong). - The instructions page shows plenty, but the app is easy to use even without. Make sure to click "1.54 inch paper B" and you'll be ready to set up your image. When done selecting and tweaking your image, simply place the tag against your phone wherever the nfc chip hides. You'll find the spot easily as the app makes a noise. Would do perfect as a gift if you can provide that info! It should really come explained in the box.... But it doesn't.

I downloaded the app “NFC E tag”, tried it for 2 hours and didn’t work. It loaded till the “Update” part but then it didn’t work. Very disappointed.

Le tag ne peut pas être programmé avec un S23Ultra.

Bastante útil día a día... Perfecto para meter un qr y usar por ejemplo como una tarjeta de fidelizacion en el supermercado o una tarjeta de visita.

An diesen Produkt hat mir das kompakte Aussehen mir gefallen und mit diesen kann man kleine Bildchen als auch Namens-Adressanhänger verwenden Was mir nicht ao gefallen hat ist die zu kleine Öse mit den der kleine Anhänger an Schlüsselbund angehangen werden kann Für dicke Schlüsselringdrähte ist das Ösenloch zu klein Bei dünndrahtigen Schlüsselringen passt der kleine Anhänger prima Funktioniert bei Smartphones,die NFC habem,mit ebenen Rückseiten Die dazu gehorige App bietet nach dem offnen eine Auswahl-Übersichr von allen bisher erschienenen EPaper-Formate an Je nach welchen EPaper&Format man ausgewahlt hat kann Bildeffekte bei Bildern erstellen Bei Texten kann man Schriftstil und Größe an das jeweilige Format anpassen Die NFC Verbindung klappt perfekt um den Schlüsselanhänger mit der Waveshare-App mit Bildchen und Text zu transferieren Nach einer langen Nutzungszeit am Schlüsselbund brach die Schlüsselringloch ab Ich hätte mir einen stabileren robusteren Schlüsselringloch gewünscht
