Principles behind sales suppression prevention
Anti-sales suppression system design
- 1. A document acknowledging that a payment has been made must contain sufficient transactional data to confirm proper tax calculations.
- 2. A document must be safeguarded by electronic signature produced by associated secure element, which uses encryption to confirm that issued document is authentic and manipulation free.
- 3. A secure element used for signing payment documents, must be independent from the creator of the automated tax calculation system designed to serve business needs of the user (invoice system).
- 4. A secure element and invoice system can be used as separate products or integrated into one product and be available in any place at any given time.
- 5. Work between secure element and invoice system must be optimized in a way to avoid any delay in producing the document.
- 6. System must be personalized in such way that either document that it produces clearly identifies the issuer.
Verification of document integrity, inspection and audit
- 7. An inspection conducted in simplest form must immediately provide information about the integrity of the payment document.
- 8. Simple on spot-inspection does not require authorized personnel or sophisticated technical knowledge to perform verification of encrypted data.
- 9. Authorized personnel follow a unified method to inspect the secure element from which information about each transaction can be extracted, preferably in encrypted form.
- 10. Electronic journal records in human readable form, must be provided for the user through the invoice system or made available through secure element data collector.
- 11. Verification services to authenticate documents for both authorized personnel and the public must be available at any time, preferably online, and in various media types.
Leveling the playing field for all suppliers
- 12. Requirements for compliance must be transparent to allow a level playing field for all suppliers to offer their products.
- 13. Variety models of invoicing systems must be made available to accommodate different business needs.
- 14. Information on payment documents, in both printed and electronic form, has to be unequivocally presented to the client.
- 15. In business-to-business transactions, unique identity of purchasing party must be safeguarded from any modifications by electronic signature.
