Payments then go offline.
Its service is based on software technology originally developed by an industry group called the Financial Services Technology Consortium. A company signs up for Clareon's service and downloads a small browser plug-in that digitally signs and encrypts file output from the company's accounts payable program. Via a Secure Sockets Layer connection, the files are passed to Clareon's server program for processing. The information is decrypted, then Clareon inserts a payment authorization and hands it to the ACH for final settlement by the banks, which debit one account and credit another to settle the transaction. Clareon participants can also use the service to make and accept payments with each other directly, without using an exchange in the middle.
