Security precautions:
1. Guest credit card details should be encoded in the PMS. Only authorized employees should be able to view guests’ full credit card details.
2. Credit card numbers should be truncated on all pre-authorizations and credit card receipts.
3. Pre-authorizations and credit card receipts must be kept in a secured place with restricted access. When the archiving period required by the local regulation has passed the receipts must be destroyed.
4. The use of manual credit card machines (or zip-zap) must be exceptional. The access to such machines and manual credit card slips must be restricted.
