Most Korean credit cards carry a built-in NFC chip. By tapping the card, this prototype delivers personalised basics (weather, tweets, headlines), exploring the idea that a credit card is not just a payment device but a part of your identity that can extend to other services.
Most Korean credit cards already contain an NFC chip used for payment and identification. This prototype asks a bigger question: what if the card is a part of your identity, not just a way to pay?
By tapping the card, the prototype surfaces personalised basics (weather, tweets, headlines) tuned to the holder's preferences. It's a small demonstration of a large idea: the card as a personal key that can extend to services well beyond the transaction.
The working prototype hints at a future where one familiar object (the card already in your wallet) becomes a lightweight, personal gateway to information and services.
