​
There are two types of authorization scenarios:

  • Dual message (DM): In this scenario, the merchant’s bank initiates an authorization request to the issuer to reserve funds for later clearing. The reserved funds will be shown in your reserve balance. The funds are only deducted when the merchant sends the clearing request. If the clearing request is not initiated in a timely manner, the transaction is reversed and the funds are released back to you..
  • Single message (SM): The authorization and clearing requests are effectively combined into one final message and the requested amount will be deducted from your balance straight away.
