A pioneer in the industry, the client is one of the leading providers of prepaid debit cards in the United States. Its prepaid cards offer financial freedom and convenience to more than 100 million unbanked and underbanked U.S. consumers. Through major retail partners like grocery stores, the company has provided pre-paid debit cards to millions of Americans. Recently, it diversified its business model by offering cards directly to consumers. The biggest concern: mailing offers to individuals who are already customers through one of the company’s partners. Because the card issuer mails reloadable debit cards to prospects — more costly than just paper mailings — the company needed to clean its database and identify duplicate records to reduce direct marketing costs.
