Europe’s unattended retail sector is becoming a testing ground for new digital payment technologies. In Germany, vending machine manufacturer Stüwer and payment service provider VR Payment have introduced Wero payments without requiring additional card terminals. Comparable partnerships involving Payconiq in Belgium, Swish in Sweden, Vipps MobilePay in Denmark and BLIK in Poland illustrate how national and emerging pan-European payment systems are being integrated into vending machines and other self-service environments. Although these solutions differ in their technical architecture and commercial deployment, they reflect a common development: payment acceptance is increasingly becoming a software-controlled function of connected retail infrastructure.

The expansion of digital payment methods is changing the requirements placed on automated sales systems. Traditional vending machines relied primarily on coins, banknotes or dedicated card readers. Modern installations increasingly combine touchscreen interfaces, online connectivity, remote management and payment processing within a single technical environment. This creates opportunities to introduce additional services without extensive hardware modifications, but it also makes the reliability of digital communication and transaction processing essential to everyday operations.

For operators, the choice of payment technology is therefore becoming both a commercial and a security decision. Beyond transaction fees and customer acceptance, companies must consider integration costs, network availability, payment authentication and the handling of transactions that cannot be completed as intended.

Germany: Wero enters physical retail through an e-commerce connection

The latest development comes from German vending machine manufacturer Stüwer and payment service provider VR Payment. On 30 October 2026, the companies announced that Wero had become available for compatible connected food vending machines, including models in Stüwer’s sVenT range.

The integration allows customers to pay directly from their bank accounts using a Wero-enabled banking application. After selecting a product, they choose Wero as their payment method and scan a dynamically generated QR code displayed on the machine’s touchscreen. The payment is authorised on the customer’s smartphone, and the machine receives the corresponding confirmation before dispensing the selected product.

The distinguishing feature is the underlying technology. Although the transaction takes place at a physical vending machine, it is processed through Wero’s existing e-commerce infrastructure. According to VR Payment, a digital checkout operates in the background, receiving the product selection, preparing the payment information and generating the transaction-specific QR code. The arrangement effectively connects an unattended physical sale to an online payment process.

This enables Stüwer to offer Wero before the wider introduction of a dedicated German point-of-sale solution. It also means that compatible machines can be upgraded without installing an additional card terminal. Provided the machine has a touchscreen and permanent internet connectivity, the payment option can be activated remotely following the necessary acceptance agreement with VR Payment.

The commercial benefit is particularly apparent for machines without existing electronic payment hardware. For operators already accepting cards, Wero adds another payment option rather than necessarily replacing established methods. Whether it reduces total payment costs will depend on transaction charges, existing equipment and operating conditions. The partners have not published a comparative cost analysis.

The cooperation builds on an established relationship between Stüwer and VR Payment, which already supplies payment services for the manufacturer’s REGIOMAT and HOTELMAT automated retail concepts.

Belgium: Coca-Cola and Payconiq demonstrated QR-based vending payments

Belgium offers an earlier example of mobile payment integration in the vending industry. In November 2021, Bancontact Payconiq Company and Coca-Cola European Partners announced a partnership to introduce Payconiq payments at Coca-Cola vending machines.

Under the proposed arrangement, customers could scan a QR code attached to the machine using the Payconiq by Bancontact application or a compatible banking app. They could then select a drink and confirm the payment through the PayDrink platform. The companies announced plans to extend the service to 2,000 vending machines during 2021.

The Belgian approach differed from the Stüwer implementation in its use of a printed QR-code sticker rather than a dynamic payment reference generated on the machine’s display. Both methods connect a physical purchase to a mobile payment environment, but they require different arrangements for identifying and processing individual transactions.

The announced Coca-Cola deployment provides evidence of an established commercial application of mobile payments in vending. However, the original announcement does not independently establish how many machines ultimately received the service or remain operational today.

Belgium’s payment market has also continued to evolve. In March 2026, the merchant-facing Payconiq service was renamed Bancontact Pro, reflecting changes in the company’s wider payment offering. The earlier vending cooperation therefore represents an important predecessor to the more recent development of European QR-based payment services, rather than evidence of a direct Wero integration at Coca-Cola machines.

Sweden: Nayax integrates Swish into unattended payment devices

In Sweden, the development of mobile payments in unattended retail has followed a different technological route.

In March 2021, payment technology provider Nayax announced that it had received technical supplier certification from Swish, Sweden’s widely used mobile payment service. Working with its local partner VP Salestech, Nayax enabled Swish transactions through its VPOS Touch payment devices.

Customers can scan a dynamically generated QR code displayed on the Nayax terminal and authorise the transaction through the Swish application. The integration was designed for a range of unattended environments, including vending machines, laundromats, car washes and entertainment equipment.

Unlike the new Wero arrangement, the Swedish solution relies on dedicated payment acceptance hardware. It nevertheless demonstrates how an established domestic banking-based payment service can be incorporated into automated retail equipment alongside conventional card schemes.

The original announcement confirms the technical certification and commercial availability of the integration, but does not provide a verified total of machines operating with Swish. Its significance lies primarily in the cooperation between a national payment network, a specialist payment technology provider and an established unattended retail distribution channel.

For operators, the Swedish model illustrates an important consideration: supporting a payment method already familiar to consumers may be commercially useful even when additional hardware or integration arrangements are required.

Denmark: Vipps MobilePay supports QR payments through dedicated vending controllers

Denmark provides a further example of mobile payment acceptance at unattended sales locations.

SwitchPay offers a vending solution using Vipps MobilePay, the Nordic mobile payment platform. Its system combines a printed QR code with a controller connected to the vending machine. Customers scan the code with their smartphones, select a product and approve the transaction through the Vipps MobilePay application.

According to SwitchPay’s technical description, the controller connects to the vending machine through the Multi-Drop Bus (MDB) interface, a commonly used communication standard for vending equipment and payment peripherals. Network connectivity can be provided through LAN, Wi-Fi or mobile communications.

The arrangement does not require a conventional contactless card terminal for app-based payment acceptance, but it does depend on additional control hardware. This distinguishes it from Stüwer’s software-based activation on compatible machines and from solutions incorporating QR-code functions into existing payment terminals.

Vipps MobilePay also provides developers with documented payment flows using static and dynamic QR codes. These support different equipment configurations, including machines with or without customer-facing screens.

The technical documentation highlights the importance of distinguishing payment authorisation from the final processing of a transaction. A payment request may be approved before the system completes the corresponding sale, making reliable status verification essential. The precise sequence depends on the payment flow and processing arrangement used.

SwitchPay’s offering is a commercially advertised vending solution. Public product information does not, however, establish its installed base. The Danish example is therefore most useful for understanding the range of available technical architectures rather than measuring market penetration.

Poland: BLIK moves towards software-based acceptance

Poland illustrates another route into unattended retail, based on the country’s established BLIK mobile payment system.

On 29 January 2026, payment provider Viva.com and BLIK announced the introduction of six-digit BLIK code payments through Viva.com’s Tap on Any Device technology. The service enables merchants to accept payments through the Viva.com Terminal application on compatible equipment, including smartphones, tablets, kiosks and vending machines.

Instead of scanning a QR code, customers generate a payment code within their supported banking application and use it to authorise the transaction. The integration brings a familiar national payment method into a wider range of physical retail environments.

The commercial proposition differs from the earlier examples. Rather than requiring a separate conventional payment terminal, Viva.com aims to integrate acceptance capabilities into software running on compatible connected devices. The approach can reduce the need for dedicated payment equipment in suitable applications, although it does not remove the underlying requirements for secure hardware, connectivity and system integration.

The announcement confirms that BLIK code acceptance has been introduced to the platform and is supported for vending and kiosk applications. It does not establish the number of vending machines currently using the service.

The Polish cooperation illustrates how domestic payment systems can expand through partnerships with technology providers offering broader European acceptance infrastructure. It also demonstrates that software-based payments need not depend exclusively on QR codes.

European payment integration remains fragmented

These developments are taking place alongside wider attempts to connect Europe’s national payment environments.

The European Payments Initiative, which operates Wero, aims to establish a common account-to-account payment service capable of supporting transactions across participating European markets. Its rollout remains gradual, with different payment functions available in individual countries.

On 26 October 2026, EPI began introducing Wero e-commerce payments in the Netherlands as part of the planned migration from iDEAL. The transition is expected to continue until the end of 2027. Wero point-of-sale payments are already available in Belgium and Luxembourg, while deployment in other countries remains at different stages.

The Dutch development is relevant to the wider European payment market, although it should not be confused with a specific vending machine integration.

The four national examples also show that Europe has not yet converged on a single technical model for unattended payment acceptance. Operators may encounter dynamic QR codes, permanently displayed codes, payment applications integrated into existing terminals, additional machine controllers or software-based acceptance platforms.

Each arrangement has different implications for installation, maintenance and integration. An operator managing vending equipment across several countries may therefore need to support multiple payment systems, technical interfaces and service providers.

Hardware costs are only one part of the commercial calculation

The move towards software-based payment acceptance is partly driven by the potential to simplify the introduction of new services.

Where compatible machines already have suitable screens, connectivity and processing capabilities, additional payment methods can sometimes be introduced without replacing equipment. This may reduce installation work and avoid expenditure on dedicated terminals. Remote activation can also simplify deployment across geographically dispersed machine networks.

Other solutions require payment devices or controllers but may offer advantages in compatibility, established support arrangements or the ability to accept several payment methods through the same hardware.

The economic comparison extends beyond equipment costs. Transaction fees, service subscriptions, network connectivity, software maintenance and technical support all influence the total cost of payment acceptance. Operators also need to consider the popularity of individual methods among customers.

A payment service widely used in Sweden may be less relevant at a retail location in Germany. Conversely, a pan-European solution could offer advantages to operators serving customers from several countries, provided the necessary banking and merchant acceptance arrangements are available.

The published cooperation announcements do not provide sufficient comparable cost data to determine which technical model is economically preferable. Nevertheless, they demonstrate that payment acceptance is becoming an increasingly important element of vending machine procurement and lifecycle management.

Transaction integrity and operational resilience become decisive

As vending machines become more closely connected to external payment services, security requirements extend beyond the authentication of the customer.

For unattended retail, the critical process is the reliable association of a purchase with its corresponding payment. The vending controller must distinguish between transactions that have been initiated, authorised, completed, cancelled or interrupted. The machine must also avoid releasing products in response to incorrect, duplicated or otherwise invalid payment information.

Dynamic QR codes offer the advantage of providing transaction-specific references. Static codes can simplify installation, particularly on machines without displays, but require appropriate safeguards against physical replacement or manipulation and reliable association with the subsequent payment request.

Neither arrangement is inherently sufficient to guarantee transaction security. The integrity of the displayed information, the protection of communication interfaces and the verification of payment status remain essential.

The documented Vipps MobilePay payment flows illustrate why these distinctions matter. They describe separate steps for payment requests, authorisation, processing and confirmation, with the merchant’s system responsible for correctly interpreting the resulting status.

Operational problems create a further challenge. A customer may successfully authorise a payment even though the machine subsequently fails to deliver the selected product. Such failures require reliable correction, cancellation or refund procedures.

VR Payment states that the Wero implementation addresses failed dispensing operations by adjusting the amount charged when the machine detects and records an unsuccessful delivery. This is a relevant feature for unattended retail, where immediate assistance from staff is generally unavailable. The publicly released information does not, however, provide a complete technical account of every possible failure scenario.

The ability to activate payment functions remotely also makes device management increasingly important. Access permissions, software updates, communication failures and the availability of external payment services all affect operational reliability.

For larger operators, particularly those managing equipment across different countries, this creates a need for consistent security policies even when the underlying payment systems differ. Technical standardisation at the device and management level may become as important as the adoption of individual payment methods.

Outlook: A more connected market, but no single European solution yet

The cooperation between Stüwer and VR Payment is a recent example of a wider development already visible across Europe. Earlier initiatives involving Coca-Cola and Payconiq, Nayax and Swish, and SwitchPay and Vipps MobilePay demonstrate how mobile payments have entered unattended retail through different commercial partnerships. Viva.com’s integration of BLIK adds a more recent software-based approach.

Their implementation stages and technical capabilities are not directly comparable. Some represent established product offerings, others announced deployments or newly introduced integration capabilities. They nevertheless reveal a common direction: payment acceptance is becoming more closely linked to the software and connectivity of automated retail equipment.

For operators, this creates opportunities to introduce additional payment methods and adapt services to local consumer preferences. For manufacturers and payment providers, it increases the importance of reliable interfaces and interoperable system architectures.

The next challenge for Europe’s unattended retail industry is therefore not simply to provide more payment methods. It is to integrate them economically and securely across different markets while maintaining reliable transaction processing, manageable operating costs and consistent protection of connected equipment.
