This module allows ZenCart to work successfully with Quantum Payment Gateway. This ZenCart payment module interfaces with the Quantum Gateway Transparent Database Engine for those merchants who collect and/or store all their customers' information. Most uses for this are automated billings. By using this method the merchant can process the transaction from their website to a Quantum Payment Gateway without their customers seeing it.
