Pi eCard is a one-stop utility that allows you to easily send and consume your Pi. Our convenient offline transactions allow for the use of simple, scannable QR codes or URLs to issue invoices to other developers. This creates a fast and universal POS (Point of Sale) system to assist in face-to-face or online transactions between developers, thereby helping the entire Pi ecosystem.

In the Pi ecosystem, there are many pioneer groups meeting regularly to discuss and plan the use of Pi coins. Many people in these groups hope to accept Pi in their stores or services, but currently to achieve this, they must share their long public key, and customers must input it into their wallets, which may lead to errors that invalidate transactions, or worse, losing the hard-earned Pi.

Our on chain or off chain automation assisted dApp aims to address this issue. To register our application, Pioneer only needs to access pi://piecard.app in the pi browser and allow pi authentication.
