Purpose of the system
GMOEBYS allows businesses to make sales through mobile devices such as smartphones or tablets, without using a cash register (OKC), and to issue the financial documents for those sales electronically. This allows small businesses in particular to meet their legal obligations without purchasing a separate cash register device.
How does it work?
- The sale is made through the application on the mobile device.
- Payment is collected by card or other methods.
- The financial document for the sale is generated electronically.
- The document is transmitted to the Revenue Administration through the system and stored.
Importance for payment systems
GMOEBYS ensures that the payment and the financial document are created within the same process. This structure makes it easier to keep card payments on record and keeps businesses' sales and collection records consistent. It also paves the way for the wider adoption of mobile POS and phone-to-POS solutions.
Service providers
Businesses that want to use the system use the services of one of the system providers authorized by the Ministry. These providers may be financial institutions, cash register (OKC) manufacturers, or private integrators.
