Advertising kiosks Self-service payment Kiosk stands

The K5 advertising kiosk and self-service payment kiosk stand is a versatile self-service terminal designed for businesses that need interactive digital displays, contactless payment, barcode scanning, receipt printing, and customer-facing services in one compact device.

With a 21.5-inch industrial-grade HD touchscreen, integrated thermal printer, RFID/NFC reader, optional EFT-POS payment terminal, barcode scanner, and facial recognition options, the K5 can be configured for a wide range of self-service applications.

It can be installed on a checkout desk, mounted on the floor, or attached to a wall. This flexible design makes it suitable for retail stores, restaurants, hotels, transportation facilities, ticketing locations, commercial buildings, and other environments where customers need to complete transactions or access information without direct staff assistance.

What Is the K5 Self-Service Kiosk?

The K5 is an Android-based interactive kiosk that combines a large touchscreen with multiple optional payment and identification technologies.

Instead of using separate devices for displaying information, accepting payments, scanning codes, reading contactless cards, and printing receipts, businesses can integrate these functions into one self-service terminal.

The 21.5-inch vertical display provides enough space for menus, product information, advertisements, payment instructions, and interactive applications. The touchscreen allows customers to navigate the interface directly and complete tasks without using a traditional keyboard or mouse.

The modular design also allows businesses to select the peripherals they actually need.

Specifications

21.5-Inch Interactive Touchscreen

The K5 uses a 21.5-inch industrial-grade HD touchscreen with a 1080 × 1920 resolution.

The large vertical screen provides sufficient space for interactive menus, promotional content, product information, instructions, advertisements, and payment interfaces.

For self-service applications, screen size is important because users need to see both the current operation and the available choices without excessive navigation.

The touchscreen can also help businesses combine advertising with transactions. For example, a restaurant can display promotional content before showing its ordering interface, while a retail store can promote products before directing customers to payment.

Integrated 80 mm Thermal Printer

The K5 supports an 80 mm thermal printer with an automatic cutter.

The printer supports paper rolls up to 80 mm in diameter and provides a printing speed of up to 150 mm/s.

This makes the kiosk suitable for applications that require physical receipts, tickets, transaction records, queue numbers, or other printed information.

An integrated printer can reduce the need for an external receipt printer and simplify kiosk installation.

RFID and NFC Contactless Card Reading

The K5 can be equipped with a contactless card reader supporting ISO14443 Type A/B, Mifare, and ISO18092.

This provides a flexible platform for applications that require RFID or NFC-based identification and interaction.

Depending on the application and software configuration, the reader can be used for membership identification, access-related workflows, customer authentication, contactless transactions, ticket validation, or other RFID-enabled services.

The exact payment functions depend on the selected payment hardware, software, acquiring bank, and local payment requirements.

Optional EFT-POS Payment Integration

For businesses that require electronic payments, the K5 supports an optional TPS900 all-in-one EFT-POS solution.

Integrating payment hardware into the kiosk can create a more streamlined customer journey:

Select a service → Confirm the order → Make a payment → Print a receipt

This approach can reduce the number of separate devices required at the service point.

Because payment requirements vary by country and application, businesses should confirm supported payment methods, certifications, acquiring requirements, and software integration before deployment.

Optional Barcode and QR Code Scanner

A 1D/2D barcode scanner can be added to the K5.

The scanner can be used for QR codes, barcodes, tickets, coupons, membership codes, product information, and other machine-readable data.

The K5 supports different scanner window configurations, including small-window and large-window options.

This is particularly useful when customers already have information stored on a smartphone. Instead of manually entering a code, they can simply present the barcode or QR code to the scanner.

Optional Facial Recognition

For applications that require customer identification, the K5 can be configured with different camera options.

Available configurations include:

• Single-lens camera
• Dual-lens camera
• 3D depth-sensing camera

Facial recognition should be implemented according to the requirements of the specific application and applicable privacy and data protection regulations.

For example, a deployment may use camera technology for identity verification, controlled access, membership services, or other authorized customer identification workflows.

Flexible Communication Options

The K5 supports multiple communication methods, allowing it to be deployed in different network environments.

Standard communication options include Wi-Fi, Bluetooth, and Ethernet. Optional cellular connectivity is also available through LTE, WCDMA, or GPRS.

The choice of connectivity depends on the installation environment, network infrastructure, and application requirements.

Three Installation Options

One of the advantages of the K5 platform is its flexible mounting design.

Businesses can choose a checkout desk configuration, floor stand, or wall-mounting bracket depending on the available space and customer workflow.

The installation method should be selected according to the height, viewing angle, accessibility, cable routing, and customer traffic of the deployment site.

Advertising Kiosk vs. Self-Service Kiosk

The K5 can be used as both an advertising display and an interactive self-service terminal.

A conventional digital advertising screen primarily presents content. A self-service kiosk, by comparison, allows the customer to interact with the system and complete a task.

The K5 combines these two concepts.

This combination can be valuable for businesses that want to generate promotional exposure while also providing a practical self-service function.

K5 vs. Separate Peripheral Devices

Another advantage of an integrated kiosk is that several functions can be consolidated into one customer-facing unit.

A customized K5 configuration can therefore help simplify the physical layout of a self-service station.

However, the final system still requires appropriate software integration between the kiosk, payment system, backend platform, and business application.

Applications of the K5 Self-Service Kiosk

The modular hardware configuration allows the K5 to support many different applications.

Retail Self-Checkout

Retailers can use the touchscreen, barcode scanner, payment terminal, and receipt printer to create a self-service checkout workflow.

Customers can scan products, review their order, complete payment, and receive a printed receipt.

Restaurant Self-Ordering

Restaurants and quick-service businesses can use the large touchscreen for digital menus and self-ordering.

The kiosk can display food items, options, prices, promotions, and order information before directing the customer to payment.

Ticketing and Check-In

The combination of touchscreen, QR/barcode scanner, RFID reader, and printer can support ticketing and check-in applications.

Customers can scan a ticket or code, verify information, complete the required process, and receive printed confirmation when needed.

Hotel and Hospitality Services

Hotels and hospitality businesses can use self-service kiosks for customer check-in, information services, membership identification, or other guest-facing applications.

The exact workflow depends on the hotel management software and connected backend systems.

Membership and Loyalty Services

The RFID/NFC reader and optional barcode scanner can help customers identify themselves using cards, tags, or digital codes.

The kiosk can then connect the identification process with a membership or loyalty platform.

Information and Advertising

Businesses can deploy the K5 as an interactive advertising kiosk even when payment is not required.

The touchscreen can present promotional campaigns, product catalogs, directions, service information, or interactive brand experiences.

Software Compatibility and MDM

The K5 uses Android and is designed with software compatibility and application development in mind.

The kiosk can be integrated with customized applications according to the requirements of the deployment.

Optional Mobile Device Management (MDM) support can also help businesses manage multiple deployed terminals.

For larger kiosk networks, centralized device management can be important for monitoring, application deployment, configuration, maintenance, and operational control.

The exact MDM functions depend on the selected software platform and integration method.

How to Configure the K5 for Your Project

Not every self-service application needs every available peripheral. Selecting the correct configuration can help control cost and simplify deployment.

The final configuration should be determined by the software workflow, payment requirements, peripherals, installation environment, and target market.

Why Choose a Modular Self-Service Kiosk?

A modular kiosk gives businesses more flexibility than a fixed-purpose terminal.

The K5 allows different combinations of payment, identification, scanning, printing, connectivity, and mounting options. This means the same basic platform can be adapted for different projects.

For system integrators and OEM/ODM customers, this can also make it easier to develop a kiosk solution around a specific application rather than purchasing a completely different machine for every use case.
