## Source summary

Digital Transactions reports that Sionic and Agentix launched a service in which a Sionic shopping agent can use Agentix's machine-readable merchant inventory and Sionic Instant Bank Pay to complete user-assigned purchases directly from a bank account. The payer must approve the purchase before submission, and Sionic says its fraud service scores transactions within milliseconds.

## Why it matters

This is a concrete alternative to card-only agentic checkout: it combines delegated shopping, explicit payer approval, fraud screening and real-time account-to-account payment. The launch is currently a U.S.-focused company deployment, not evidence of cross-border availability or adoption; the claimed merchant fee saving of about 60% versus cards comes from Sionic's CEO and is not independently measured.

## Key numbers

- **Claimed merchant fee reduction versus comparable card processing:** typically about 60%
