Mobile App for POS terminal functionality like offline, force sale, big transaction

Hello, I want the functionality of manual, online and offline, forced sale that processes a transaction using the 6 digit voice authorization number provided by the creditor. Transactions pre authorized by Visa, its a 201 Visa protocol.

I don't mind if you can develop android app or virtual terminal for this as long as it can do the transaction type.

What is the most important that the visa protocol is followed exactly like my attaching video.

I will share video with expert only in PM.

It's better if you can add the function that we can use merchant account and also a bank account as the funds are pre approved by visa when the forced sale manual offline 201 protocol is implemented.

Only expert i will discuss with.
