Overview

Fully Integrated Payment

Empowering Payment Innovation: One-Stop POS Integrated Payment Solution

    Provides full stack SDK interfaces from low-level hardware operations to high-level transaction services, helping you quickly build high-performance, high-security intelligent payment applications.

includes

Low-Level Hardware Interaction

• NSDK & EMVL3: Delivers fundamental hardware operation interfaces and EMV transaction standard interfaces (including EMV L2/L3) via AAR library. Supports multiple payment methods (contactless/contact/swipe) and security features (PIN entry, data encryption/decryption, etc.), comprehensively ensuring transaction security and device compatibility.

• NHAL: Provides core capabilities – hardware operation interfaces, security interfaces, and EMV L3 transaction interfaces – through Service architecture. Decouples payment applications from terminal hardware, isolates hardware failure risks, and guarantees payment application security and stability.

Transaction Workflow Engine

• PaymentService: Atomized encapsulation of acquiring transactions, integrating the entire process of transaction services such as pre-authorization, consumption, cancellation, and refund**, **with built-in risk control rule engine and asynchronous callback mechanism, supporting customized transaction strategy expansion, empowering rapid acquiring application development (reducing the cost of acquiring application development by 80%)

P2PE Security Empowerment

• PaymentLink: Certified by PCI P2PE Application, it provides end-to-end encryption payment capabilities, integrates multi-level interfaces such as NSDK/EMVL3/PaymentService, constructs a secure and agile next-generation payment hub, and significantly reduces the compliance cost and cycle of customers' P2PE Solution.

How to choose the suitable SDK?

Strategy 1: Under what circumstances should the transaction workflow engine PaymentService be selected?

    ✓ Core Value: Lower development barriers and focus on business logic

    ✓ Applicable Scenarios:

• With limited experience in the payment industry, it is necessary to quickly implement the acquiring function

• No need for in-depth customization of the trading process; reuse standardized services

    ✓ Advantages:

• Atomized encapsulation of the complete transaction process reduces API calls by 70%

• Flexible configuration engine, covering mainstream acquiring scenarios

• Shorten the development cycle by 50% and accelerate solution deployment

Strategy 2: Under what circumstances should the SDK of the underlying hardware interaction layer be selected?

    ✓ Core Value: Flexible customization, adaptable to complex scenarios

    ✓ Applicable Scenarios:

• Have experience in payment industry application development and need to deeply control device interaction

• Develop multi-vendor device compatibility solutions or proprietary HAL layers

    ✓ Interface Selection Comparison:

Strategy 3: When to Choose PaymentLink?

    ✓ Core Value: Integration of Security Compliance and Full Stack Capabilities

    ✓ Applicable Scenarios:

• Has a need for PCI P2PE Solution compliance certification (saving %xx in Compliance Evaluation costs)

• Require end-to-end encryption of sensitive data

    ✓ Technical Advantages:

• Integrate low level hardware interfaces (NSDK/EMVL3) with high level transaction services (PaymentService)

• Cardholder data is encrypted end-to-end, meeting financial-grade security standards
