Verify
A Verify transaction checks the card is authentic. No funds are checked or held.
A successful Verify transaction can have a new Sale captured from it for any amount.
Pre-Auth
A Pre-Auth transaction does NOT charge or create a temporary hold of funds, it simply checks the funds are currently there. It may however show in ‘pending' on the customer’s side for up to 24 hours.
A successful Pre-Auth transaction can have its amount charged at a later date by manually capturing it (via one of the transaction history pages). There is no guarantee however that the funds will still be available in this customers card.
Delay Capture
A delayed capture transaction DOES place a hold on the customer’s funds.
The funds will be automatically captured on the day specified, or when manually captured (via one of the transaction history pages)
Please note, some banks may release the funds early.
