The PROSEFA application allows you to control Angola's high security Tax Stamps. Inspection entities can prove the authenticity of Tax Seals affixed to products whose tax seal is mandatory. Seals read or entered by the PROSEFA application are validated on the PROSEFA Platform, which will certify the existence of the seal and its status, and return information about the product where it was affixed. The reading is recorded centrally on the PROSEFA Platform.
