List-Based Transaction Processing

By default, Simplify sends transactions to Fusebox with PCI-sensitive data fields encrypted. Simplify uses two BIN lists to control and (if desired) modify this processing:

  • Encrypt list – A non-configurable list containing BINs for PCI-protected PANs and any other BINs for which PCI-sensitive data fields can never be sent to Fusebox unencrypted. If this data cannot be encrypted, the transaction will not be sent to Fusebox and a bad card read response will be returned to the POS (no data).

  • Return list – A merchant-configurable list containing BINs which will not be sent to Fusebox. These transactions will be returned to the POS unencrypted for use as determined by the merchant. Can only include BINs not in the Encrypt list.

If in neither list, the transaction will normally be sent to Fusebox encrypted (default processing). If there is an encryption failure not caused by system failure (e.g. data too long to encrypt), it will be sent unencrypted.

note

If you want to use this list-based process to control transaction processing, please contact your Elavon representative regarding list configuration.

Sample Transaction with Return Unencrypted Response

The following sample is for a Sale transaction whose BIN is in the Return list. Simplify sends a Return Unencrypted response to the POS.

Return Unencrypted Response

The following response sends account data to the POS in the clear (API 0003). The Response Message field (API 1010) contains *SLR WHITELIST, indicating a Return Unencrypted Response. Note that API 5004 (Encryption Provider ID) is not sent since the account data is not encrypted.
