Cashu has developed an experimental NFC card that stores Bitcoin-backed ecash on a chip, allowing merchants to accept tap-to-pay transactions without an internet connection. The card uses a Chaumian ecash protocol and stores digital cash tokens on a JavaCard chip, enabling offline payments that settle later when the merchant's terminal reconnects to the network. This innovation addresses the common issue of needing internet for Bitcoin payments, though risks include loss of card balance and delayed merchant settlement. The project is part of a broader effort to enable offline and contactless Bitcoin payments.
