Why Choose a Dual-Screen POS Terminal?
A conventional POS terminal normally provides one screen for the operator. A dual-screen POS system adds another communication point at the checkout counter.
The customer-facing screen can be used to display:
- Order details
- Product information
- Prices and totals
- Promotional content
- Advertising
- Customer messages
- Transaction confirmation
This configuration is particularly useful in restaurants, cafés, convenience stores, retail shops, and other environments where customers need to see transaction information during checkout.
For businesses that do not require a customer display, the single 15.6-inch configuration offers a simpler and potentially more space-efficient solution.
Android POS Hardware Configurations
The C1 is available with different processor and operating system configurations. The original product specification lists an RK-based configuration with Android 9 and a Qualcomm-based configuration with Android 10.
| Configuration | Operating System | Processor | Standard Memory | Optional Storage |
|---|---|---|---|---|
| RK scheme | Android 9 | Quad-core 1.4GHz + dual-core 1.8GHz | 2GB DDR + 8GB eMMC | 2GB + 16GB |
| Qualcomm scheme | Android 10 | Octa-core 1.8GHz | 2GB DDR + 8GB eMMC | Up to 4GB + 64GB |
The device also provides an external TF card slot, giving system integrators an additional storage option where supported by the selected hardware configuration.
For a basic POS application, the standard memory configuration may be sufficient. More demanding applications, multimedia content, remote management, or customized software may benefit from the higher-memory and larger-storage options.
Built-In Thermal Printer
The C1 can integrate a thermal receipt printer directly into the POS terminal. This reduces the need for a separate receipt printer and helps keep the checkout counter organized.
The standard printer configuration supports 58mm paper, with an optional 80mm paper width available.
| Printer Option | Paper Width | Suitable For |
|---|---|---|
| Standard thermal printer | 58mm | Compact receipts and standard POS transactions |
| Optional thermal printer | 80mm | Longer receipts and businesses requiring wider printouts |
An integrated printer can be useful for retail receipts, restaurant orders, transaction records, and other printed POS documents.
The final printer configuration should be confirmed according to the required paper roll size, printer mechanism, software compatibility, and project requirements.
Optional Camera and Customer Interaction
The C1 can be configured with different camera options depending on the intended application.
Available configurations include:
- Single-lens camera
- Dual-lens camera
- 3D depth-sensing camera
Camera integration provides additional flexibility for applications that require visual interaction or identity-related functions. The appropriate camera should be selected according to the software application and project requirements.
Businesses considering face recognition or other camera-based functions should confirm the required SDK, operating environment, lighting conditions, data-processing method, and compliance requirements before deployment.
Connectivity and Peripheral Interfaces
A POS terminal often needs to connect with printers, scanners, cash drawers, payment peripherals, network equipment, and other accessories. The C1 provides several interfaces for connecting external devices.
| Interface | Quantity | Potential Application |
|---|---|---|
| USB | 4 | Barcode scanners, keyboards, USB peripherals |
| Micro USB | 1 | Service or peripheral connection |
| RJ11 | 1 | Compatible POS peripherals |
| RJ12 | 1 | Cash drawer or POS peripheral applications |
| RJ45 | 1 | Wired Ethernet networking |
| Audio jack | 1 | Audio peripherals |
| Wi-Fi | — | Wireless network connection |
| Bluetooth | — | Wireless peripherals |
| 4G | Optional | Mobile network connectivity |
| GPS | Optional | Location-based applications |
The exact use of each interface depends on the peripheral and software configuration. System integrators should confirm electrical specifications and compatibility before connecting third-party equipment.
POS Software Development and SDK Support
The C1 is designed not only as a ready-to-use Android cash register but also as a hardware platform for customized POS applications.
The manufacturer provides SDK support for software development, allowing businesses and system integrators to develop applications around the terminal’s hardware capabilities.
This can be useful for companies that already have their own:
- Retail management software
- Restaurant POS software
- Inventory management system
- Membership platform
- Self-service application
- Customer display application
- Order management software
- Industry-specific Android application
Instead of changing an existing software ecosystem to fit a fixed POS machine, developers can build or adapt their application to the selected C1 hardware configuration.
MDM for Remote POS Device Management
Mobile Device Management (MDM) is available as an optional service.
For businesses operating multiple POS terminals, centralized device management can simplify deployment and maintenance. An MDM solution may be used to manage Android devices remotely, depending on the supported MDM platform and configuration.
This can be particularly useful for:
- Retail chains
- Restaurant groups
- Franchises
- Multi-location businesses
- Large-scale POS deployments
The specific MDM functions should be confirmed with the manufacturer based on the required deployment environment.
Single-Screen vs Dual-Screen POS Terminal
Choosing between a single-screen and dual-screen POS terminal depends primarily on the checkout workflow.
| Factor | Single 15.6″ Screen | Dual-Screen Configuration |
|---|---|---|
| Cashier operation | Yes | Yes |
| Customer-facing information | Limited | Excellent |
| Counter space | Lower requirement | Higher requirement |
| Customer interaction | Basic | Enhanced |
| Advertising display | Limited | More flexible |
| Suitable for self-developed POS | Yes | Yes |
| Best for | Simple checkout | Interactive checkout |
A single-screen configuration is a practical choice when the POS system is mainly operated by employees. A dual-screen model is more suitable when customers need to view order information, promotions, prices, or other content.
Applications of the Android POS Terminal
The C1 can be used in a wide range of commercial environments.
Retail Stores
Retail businesses can use the terminal as a touchscreen checkout station for product sales, inventory applications, customer information, and receipt printing.
Restaurants and Cafés
The dual-screen configuration can help restaurants and cafés display order information to customers while staff members operate the POS application.
Supermarkets and Convenience Stores
The combination of a large touchscreen, multiple peripheral ports, networking, and an integrated printer makes the C1 suitable for conventional checkout environments.
Hotels and Hospitality
Hotels and hospitality businesses can integrate customized Android applications for reception, retail sales, service ordering, or other customer-facing operations.
Chain Stores and Franchises
Optional MDM support and customizable hardware configurations make the C1 suitable for projects involving multiple terminals or locations.
Customization Options
Different businesses may require different hardware configurations. The C1 supports customization through both hardware options and ODM services.
Possible configuration choices include:
- Single or dual display
- Different customer display sizes
- LED/Nixie customer display
- 58mm or 80mm thermal printer
- Different processor platforms
- Different RAM and storage configurations
- Single-lens or dual-lens camera
- 3D depth-sensing camera
- Wi-Fi, Bluetooth, Ethernet
- Optional 4G
- Optional GPS

- Customized Android POS software
ODM support can be considered when a project requires changes to hardware, software, appearance, branding, or other product specifications.
Black or White POS Terminal Design
The C1 is available in black or white. Businesses can select the color according to their store design, brand identity, or installation environment.
For chain stores and branded retail environments, the exterior appearance can be an important part of the overall customer experience. ODM customization may also be discussed when a project requires a specific product appearance or branding solution.
How to Select the Right Configuration
The best configuration depends on the POS application rather than simply choosing the highest specification.
For a basic cashier application, a single 15.6-inch display with standard memory and a 58mm printer may be sufficient.
For customer-facing retail or restaurant applications, a 15.6-inch main screen combined with a 10.1-inch or 11.6-inch second display provides a practical balance between functionality and counter space.
For applications requiring more customer interaction, advertising, or visual content, the 15.6-inch + 15.6-inch configuration provides a larger customer-facing display.
If the POS application requires mobile connectivity, remote management, camera functions, or more storage, these options can be specified during the project planning stage.
Advantages for System Integrators
For POS software companies and system integrators, hardware flexibility can be as important as the physical design of the terminal.
The C1 offers several configuration choices within the same product family, making it easier to match hardware with different customer requirements. SDK support can also help developers integrate their applications with the terminal.
For larger deployments, MDM and ODM options can provide additional opportunities for centralized management and customized solutions.
This makes the C1 suitable for projects where the customer needs more than an off-the-shelf cash register.
