Cashu introduces physical tap-to-pay card for offline Bitcoin ecash payments

An experimental NFC card stores Bitcoin-backed ecash on a chip, letting merchants accept a tap without internet and settle later Cashu wants your Bitcoin to work like a transit card. The open-source ecash protocol has introduced an experimental physical tap-to-pay card that lets users make offline payments with Bitcoin-backed ecash. The idea targets one of the oldest complaints about paying with Bitcoin at a shop counter. Lightning payments are fast, but both sides usually need to be online. Cashu’s card is built for the moment when the internet isn’t.
