Pre-Selection / Pre-Authorization Process Flow
In this example, a request to pre-authorize the consumer account for £10.00 is submitted. The decision from the issuing bank will be either
Approved (funds available) or Declined (various possible reasons
–
not detailed). Once the host completes the transaction process and
commits the single (or total) transaction of £0.99 this is then re-submitted to the Alio Pro card reader to confirm with the issuing bank. On
Commit the pre-authorized value of £10.00 is replaced by the committed value of £0.99 with the funds cleared to the merchant account and
the customer’s account will be charged for the purchase.
