Abstract:

A method and apparatus for allowing a reseller to securely access and manage scratch cards at a recharge card management system that is maintained by the service provider. The service provider and reseller users of the recharge card management system can create a scratch card batch that is associated with the reseller account identification. The service provider and reseller users can search, view and modify scratch card data based on security and accessibility. Advantageously, the reseller or distributor can only manage and sell scratch card only to its own account identification, thus protecting such transactions against fraud.
