payment cards are prepaid cards that can be used to purchase IDT products. They require only a single purchase order or credit card transaction from your purchasing group. This one-time payment can then be used as needed for IDT purchases. OligoCard payment cards can be ordered online. Once ordered, you will receive a secure PIN that you can use to unlock your credit online. Once activated, you can use these cards in place of a PO or credit card as payment. OligoCard histories and balances can be managed through the web. Also see the OligoCards Catalog Page.
