  • solution contains entering of security elements - the so called CVV2 or CVC2, which is a three-digit code usually located on the back of the reverse side of the card, in the signature stripe
  • payment gateway communicates also in English and German
  • acceptance of foreign currencies is self-evident  - at the moment we offer EUR, USD and GBP.
  • communication of the e-shop with the bank is tested before the Internet shop is put into live operation

Necessary Modifications on the Business Parter Side before Integration into the Česka sporitelna System

  • creation or modification of the form that sends out data (POST to the Česka sporitelna system)
  • modification of database (introducing necessary fields)
  • creation of "validation" and "confirmation" scripts for checking data received from Česka sporitelna against data stored in the database. Scripts must accept variables, perform the check and respond with an html string.
  • creating of the "OK" and "NOK" pages, to which the cardholder is routed by the Česka spořitelna payment system after the transaction is finished (identification number of the payment is still transferred, that is the scripts can be used for e.g. writing the transaction status into the database)
  • validation and confirmation scripts must be secured through the SSL protocol. These addresses thus start with https://
