XiTransfer

XiTransfer Secure File efficiently handles the transfer of files containing sensitive data including credit card numbers, Social Security numbers, bank account numbers, patient medical records, or similar information. Following are workflow diagrams for general XiTransfer implementations and one specifically for implementing it with SAP® Cloud for Travel & Expense (SAP-C4TE).

The following diagram illustrates the basic XiTransfer workflow:

  1. File Provider(s) submit files containing sensitive information to Worldpay XiTransfer service.

  2. A call is made to XiSecure to tokenize or detokenize the sensitive data.

  3. Tokenized/detokenized files are routed to XiTransfer for file transfer.

  4. Resulting files are provided to single or multiple file recipients. These files can be pushed or for SAP-C4TE and special cases, pulled to the file recipients.

SAP-C4TE

The following diagram illustrates an XiTransfer workflow for SAP Cloud for Travel that includes remittance functionality.

  1. XiTransfer receives expense files from associations or banks on behalf of an SAP Cloud for Travel and Expense (SAP-C4TE) customer.

  2. Worldpay immediately tokenizes sensitive data (credit card numbers).

  3. Tokenized expense files are made available for pick-up by SAP-C4TE.

  4. Customers access the expense files in SAP-C4TE and create, submit and approve expense reports. The customer's SAP ERP system may detokenize credit card numbers in the expense files.

  5. Remittance files are generated from approved expense reports.

  6. XiTransfer receives tokenized remittance files from an SAP-C4TE customer.

  7. Worldpay immediately detokenizes sensitive data contained in remittance files.

  8. Detokenized remittance files are made available to their respective banks for processing.
