Use of our Token Functions

With our API type connections, credit card numbers are tokenized in processing payments.
Through our Token Functions, merchants can safely use credit card payments without handling (or transmitting) credit card information on their servers while maintaining a degree of freedom with their payment screen.

Benefits of using our Token Functions

  • Reduced risk of data leaks
  • Supports non-retention of credit card information by merchants, recommended by the Credit Transaction Security Council
