TweezerComm follows structured payment flows to ensure secure and efficient transaction processing. These define how different transaction types are handled within the system, including transactions for loyalty cards. Understanding these flows enables client applications to integrate appropriately with the AshraitEMV Application (AEA) and optimize payment processing capabilities. The pages below provide a more detailed description of each one:

Regular Transaction

Process and authorize a payment request in a single step.

Two Phases Transaction

Split a transaction into an information retrieval step and a completion step.

Pre-Authorization (Israel)

Process and authorize a transaction, then settle or cancel it based on the payment server’s response.

Deferred Payment

Run a pre-authorization phase followed by a final authorization phase.

Split Transaction

Split a transaction’s payment across multiple sub-merchants.
