MasterCard Global Ops Security Bulletin Date: 8th Nov 2016

Security level indicators in authorisations and clearing files must match, or the settlement files will be rejected.

This change will prevent authorisations being tagged as non-secure but settled transactions being tagged as secure code authenticated.

PSP’s should check their batch transaction settlement files to ensure SLI’s match for authorisations and settled transactions, this will ensure that batch settlement files are not rejected.
