The system is applicable to VAT and other forms of taxes and fees, both for cash transactions and bank transactions alike. Results vary depending on the state of the economy at the time of implementation - from 40-50% increases in tax revenue in developed countries, up to 300-400% and more in rural and developing countries. System upgrades include registration of guests in the travel and nautical sector.
