As UNIAN reported earlier, an interdepartmental working group with the participation of Ukraine&#39;s Finance Ministry recommended that the eight registrars of payment transactions be included in the State Register for further testing before April 1. In September 2018, the SFS launched its E-Receipt system for online registration of payment transactions in test mode. It allows tax payers to register cashiers and cash registers online. All sellers of home appliances, computers, smartphones and other electronics in Ukraine have been obliged to use cash registers since May 2017.
