businesscards.io works on Android. There's no native Android app today, but you don't really need one: the website is mobile-friendly, and the sharing flows that matter (Google Wallet, NFC, QR code) are all built into Android already.
Managing your card
Open businesscards.io in Chrome, Firefox, or any other mobile browser, sign in, and you have full access to your dashboard. You can create cards, edit them, view analytics, manage your team, and update your subscription. Everything you can do on a desktop, you can do from your phone.
If you want app-like behavior, add the site to your home screen: open the browser menu and tap Add to Home Screen. The site becomes a one-tap launcher.
Adding your card to Google Wallet
On your card's share page, tap Save to Google Wallet. The Google Wallet app opens and prompts you to add the pass. Confirm and the pass is in your Wallet. After that, sharing is a tap: open Wallet, tap your card, and the QR code is on screen ready to be scanned. Full walkthrough: adding your card to Google Wallet.
Sharing your QR code
Even without Google Wallet, every card has a QR code at businesscards.io/c/your-slug. Open the card on your phone, take a screenshot of the QR, and you can show it from your photos any time. Or just open the card in your browser and rotate your phone to make the QR bigger.
NFC sharing
Modern Android phones can both read and write NFC tags. You can buy blank NFC cards or stickers, write your profile URL to them, and then a tap from any phone (Android or iPhone) opens your card. Full walkthrough: sharing your card with NFC on Android.
Sharing the link
Your card URL works in any messaging app. Share it via WhatsApp, Signal, SMS, email, Slack, anywhere. The link opens directly in the recipient's browser, no app required on their end either.
What's different from iOS
The only iOS-specific features are AirDrop (Apple-only by design) and the Apple Wallet pass (an Apple format that Android can't open). Everything else (Google Wallet, NFC, QR, link sharing) covers the same ground.
