My business has a *very specific need* to be able to process payments from our clients.
We need to locate an expert that has experience with "offline" merchant transactions that use a debit card and a bank provided 6 digit pre-authorization code. We are a US company that generally deals with international clients and banks.
An example of this kind of transaction can be seen in this article [login to view URL]
We are fine with either a merchant account with a physical terminal as long as it can process keyed-in transactions this way, a hybrid service that has a terminal and a web gateway, or an online only gateway.
Most of popular online gateways like Square, Stripe, and PayPal DO NOT have this capability.
IMPORTANT NOTE: PLEASE ONLY APPLY/BID IF YOU HAVE SPECIFIC KNOWLEDGE OF OFFLINE TRANSACTIONS.
