What is an eCash Register (ePénztárgép)?

The eCash Register (ePénztárgép) is the next-generation digital cash register system introduced by the Hungarian National Tax and Customs Administration (NAV). It maintains a real-time data connection with the tax authority. Unlike traditional cash registers, this solution can function as an application installed on a smart device, such as a tablet or smartphone. One of its main features is the ability to issue electronic receipts (eReceipts) and transmit them instantly to NAV.

The eCash Register is not just a physical device, but a comprehensive digital solution that meets the demands of modern retail and taxation.

What is the purpose of the eCash Register?

The eCash Register is designed to:

• Support tax transparency through real-time data transmission,
• Enable the issuance and secure digital archiving of eReceipts,
• Simplify the operation of commercial outlets,
• Facilitate digital customer interaction (e.g. via QR code integration with customer apps).

This system contributes to the fight against tax evasion and promotes the growth of the digital economy and eco-friendly, paperless business practices.

The role of the Fiscal Unit (AE)

At the heart of the eCash Register system is the Fiscal Unit (Hungarian: adóügyi egység, or AE), which is:

• A secure electronic data storage module,
• A mobile communication device,
• Functionally separated from the rest of the cash register system.

The Fiscal Unit ensures that every receipt and transaction is securely recorded and reported to NAV. It guarantees the system’s reliability and compliance with regulatory standards.

Integration with customer applications

One of the most advanced features of the eCash Register is its ability to interact with customer devices via QR code scanning. This allows for:

• Receiving predefined purchase requests from a buyer’s app,
• Automatically sending eReceipts to the customer’s mobile device,
• Enhancing the customer experience with features such as loyalty programs and digital storage.

This functionality is key to advancing electronic commerce and payment culture, offering businesses a competitive edge and customers greater convenience.

Hardware-based and cloud-based solutions

There are two main types of eCash Registers:

• Hardware-based devices developed specifically for the new system,
• Cloud-based software solutions that can run on smart devices like tablets or smartphones.

Both types may only be used in a live business environment if tested and approved by NAV. The approval process ensures compliance with data security and system reliability standards.

Who is the eCash Register for?

The eCash Register is especially relevant for:

• Retailers looking to digitize their checkout process,
• Hospitality providers aiming for fast, paperless receipt issuance,
• Mobile vendors and small businesses needing portable, smart device-based solutions,
• Online stores or hybrid businesses managing both physical and digital transactions in a single system.

When did the eCash Register become available?

The eCash Register has been available in Hungary since 2024. NAV is rolling out the system gradually and provides technical guidance and documentation to assist with integration. In the future, the use of eCash Registers may become mandatory in certain sectors.

Summary

The eCash Register is a new digital cash register system launched by NAV, offering real-time connection to the tax authority. At its core is a certified Fiscal Unit, which handles secure data transmission. Its compatibility with customer apps supports modern, paperless receipt issuance and enhances the overall customer experience. The eCash Register represents a major step forward in digital commerce, tax transparency, and smart business practices.
