Cellum offers third-party developers the possibility to quickly and easily integrate a cashless payment option into their mobile apps through the Plug and Pay program.

Though many businesses now have great apps to engage customers, they keep losing sales due to failing to close the purchase loop. The Cellum Plug and Pay SDK allows you to do just that. It uses the same payment engine that has been powering the mobile wallets of several major financial institutions and carriers across the globe for years.

Cellum’s off-the-shelf solution is a service package that contains:

  • the core payment engine;
  • the Split Secret card vault;
  • international payment processing provided by our partner Kalixa;
  • documentation;
  • technical support.
