White Label Credit Cards, Private Label Credit Cards

Private label cards can only be used at Merchant's outlet because merchant's own network is used to process the purchases where as White label card is launched by Merchant in association with Issuer and Visa/Mastercard and it does not hold the name of issuer and it can be used at any outlet or through internet just like any other normal credit card.
