CUPay by American United app for iPhone and iPad

STI, or Secure Transaction Image, is an emerging standard in modern mobile payments. Whether paying for purchases at your favorite local merchant, splitting the ticket after dinner with friends, or sending money to the grandkids for their birthday, STI is the fast and secure option you’ve been looking for. Unlike other funds transfer methods, sending funds via STI means you can securely transfer funds via mobile device or email without worry. Unlike traditional payment methods, paying with STI means your account and card numbers are not shared with the recipient. None of your sensitive information is stored in the STI image itself meaning that it can be safely sent via email without risk of compromise. Users and merchants benefit from instant availability of funds when transferring between in-network accounts. And everyone benefits from cost savings using a secure network built to connect directly to local financial institutions.

CUPay is one part of a rapidly growing nationwide network of consumers, credit unions, community banks, and local merchants who have decided to take back the payment process and reinvent how they access their money.
