How I built a QR business card generator with Next.js

I built a QR business card generator with Next.js to solve the problem of outdated and hard-to-track printed visiting cards. The digital business card can be updated anytime and accessed through a single link or QR code. It works on WhatsApp instantly and is accessible on mobile devices. The generator uses Next.js, Tailwind CSS, and a QR code generation library. It's now live at https://digitingcard.com.
