What is SFA (Secure Financial Application) or VUK 507?
GMU (Secure Financial Application) or VUK 507, is a legal regulation that requires businesses to carry out payment collection transactions in accordance with the legal rules specified by the Revenue Administration and to electronically create, transmit, and store the documents of these transactions to the relevant institutions.
What are the responsibilities of GMU in businesses?
The Secure Mobile Application (GMU) e-Certification System ensures that all transactions start and end securely. Additionally, it is the main application that operates centrally with other applications and includes all endpoint software.
With the GMU regulation, all shopping activities can be carried out using a payment recording device and allows for the electronic documents created at the end of the transaction to be queried and accessed from the GIB system when needed. For this purpose, businesses only need to have a certified or uncertified device.
