North American pay by bank is our core
One of 150+ payment methods

Adyen is a global enterprise platform with 150+ payment methods, a US branch license and FedNow certification, so its card processing and payouts are strong. Its US pay by bank is a thinner layer. Pay by Bank (US) is powered by Plaid, merchants must register with Plaid before go-live, and payments settle as ACH debits. Returns post as chargebacks that merchants can’t defend, and there is no deposit guarantee: Adyen’s answer to return risk is Plaid’s balance and risk checks at authorization.

Aeropay fills that gap. Enterprises keep Adyen for cards and add Aeropay for bank payments: Aerosync links the account, ACH deposits are 100% guaranteed, Guard scores each transaction in real time and predictive recapture recovers more of what fails.
