BLK CARDS is a product of Melting Pot Ltd a technology company headquartered in Hong Kong. Melting Pot is a member of the NFC Forum and our aim with BLK CARDS is to bring the convenience of NFC technology to life for users around the world and change the way people connect, network and share digital information in real life interactions.

BLK CARDS provides a smarter and more sustainable technology replacement to traditional business cards with NFC digital business cards and a free mobile App "BLK CARDS" on the App stores for Android and iOS.

With the App, you can easily create a list of unlimited links that represent your digital life (for example your websites, portfolios, WhatsApp, contact vcard, social media, podcasts, videos, channels, playlists, songs, albums, NTFs, LinkedIn etc...). You can then pick and choose what digital information you want to share with new people you meet in person, and share it in just one tap of your NFC card with their smartphone (see examples).

When you meet someone new for the first time, in a social or business context, you cannot share any digital information without these steps: You first add them to your contacts, or you spell out names, social media usernames, phone numbers, or email addresses.

We made it fast, efficient and contactless. They just touch your NFC card with their NFC-enabled smartphone. Your link will open instantly and automatically on their phone. You can now share any URL, in just one tap!

We are changing the way people connect, network, and share digital information in real life.

Install the Free mobile App BLK CARDS (for Android and iOS) to easily manage your NFC digital business cards. The app is simple, intuitive and free. Try it out!

Traditional business cards will be inevitably replaced by NFC digital business cards because people print tens of millions of business cards every day, and 90% are thrown away in less than a week. This is such a waste of money, and paper, but also missed opportunities. The future is BLK CARDS, digital business cards with integrated NFC technology.
