Worldpay Non-EMV Data Flow

Critical Information
  1. Your WorldPay account must have "PASS" enabled. Be sure to let your Worldpay rep know this. This is what allows card tokenization, a critical part of your credit card data security.

  2. To ensure that credit card tokens are maintained for an appropriate length of time, be sure that the line below is added to the configuration file, MENUINI.FIL, in your Exec/Tech software folder:


    This shows our recommended default of 30 days for Guest History and 270 days for everything else. The number of days can be changed. If this is not done, the credit card tokens will not be saved and cards that have been tokenized will have to be swiped again when used.

  3. Execu/Tech Systems, Inc. software DOES NOT STORE CREDIT CARD NUMBERS. We only store a token that's returned by Worldpay. The token does not contain the credit card number. Execu/Tech does not have access to the credit card numbers of your guests and cannot provide them to you. If you need to see a credit card number, you must contact Worldpay for assistance. 


It's important to understand the flow of data between Execu/Tech Systems software and Worldpay. This understanding can help you determine if you are PCI compliant and can allow you to provide accurate information during a PCI audit.


If the proper procedures are used, there will never be any sensitive cardholder seen by, or stored in, Execu/Tech Systems software. To ensure that this is always true, you should never enter credit card data into comment, reference or note fields.


   Non-EMV Flow of Credit Card Data
  1. Cardholder data is captured, either by a card reader or manual entry, in a secure web page and posted via HTTPS to Worldpay.
    You are required to use P2P Encryption via encrypted card readers provided by Worldpay Payment Services.

  2. The Worldpay service returns to us a token consisting of a randomly generated alphanumeric string. The token is saved by Execu/Tech Systems software and is only usable between Execu/Tech software and Worldpay. Execu/Tech Systems software will only see the token. We never see the secure cardholder data and do not store the cardholder data.


    If this is a Pre-Authorization, then the flow of data stops here.

    Sales, checkouts, voids, etc. will follow the rest of this data flow.

  3. To complete the payment, void, etc., Execu/Tech Systems software submits the transaction to Worldpay using this token.

  4. Worldpay will submit this transaction to the back-end processor.

  5. The back-end processor will return the result of this transaction to Worldpay.

  6. Worldpay will return the result of this transaction, and Execu/Tech Systems software will deal with it accordingly, whether it be a success, card declined, needs voice authorization, etc.
