Giftango Corp. has expanded to more than 1,000 the number of merchant locations that use its service to sell proprietary "virtual" gift cards online, according to the Portland, Ore.-based company. An agreement announced last week with prepaid card processor Valutec Card Solutions LLC added an additional eight merchant locations and should result in more contracts by the end of the month, Mike Fletcher, Giftango chief marketing officer, tells CardLine sister publication ISO&Agent Weekly. Giftango also has processing relationships with such companies as Chase Paymentech LLC, Givex Corp. and Heartland Payment System Inc.'s Chockstone unit. Additionally, the company recently began working with independent sales organizations to resell its products, says Fletcher. With Giftango's service, merchants sell closed-loop prepaid products from their Web sites. Buyers receive e-mails with a link to a Giftango Web page that shows the amount of funds available in the card account, a bar code and the card number. To use the service, consumers either can print the information from the Web page and take it to a retailer, or they can open the page using a smartphone Web browser and show the information to the clerk at the point of sale. The merchant then either enters the prepaid account number at the point of sale or scans the barcode to access the funds for a transaction. Valutec, which processes gift card payments for more than 38,000 U.S. merchant locations, was unable to respond to a request for comment by CardLine deadline.
