No, They Don't:

The receiver does not need to have a digital business card to view your contact information. Anyone can access your Wave digital business card via a browser (like Safari or Chrome) without needing to download an app or create a Wave account. This makes it easy and convenient for anyone to receive and view your contact details instantly.

By simply tapping your Wave NFC product or scanning the QR code, recipients can directly access your digital business card using their smartphone, ensuring a seamless and hassle-free experience.
