No, you don't need an app to use or view a Wave Connect Digital Business Card. Once someone shares their digital business card with you, you can easily access all their contact information directly through a web browser on any device. There is no need to download an app, create an account, or install any additional software.
If you're sharing your own Wave Connect Digital Business Card, you can share it using a QR code, a link, or even Wave Connect NFC products. These can be shared via email, SMS, or simply shown in person for scanning. The person receiving your card can view it instantly without needing to download anything.
Additionally, if you save your digital card's QR code as wallpaper or in your phone’s wallet, you can share it offline, too. While the receiver will need internet access to fully load the page, they don’t need an app to get your details.
What the other person sees on iPhone
When someone taps or scans your card with an iPhone, iOS may first show a small preview card (an App Clip) before your profile opens. They do not need to install anything: see The App Clip Preview When Someone Taps or Scans Your Card (iOS) for how that preview works.
