Specification

Bluetooth and USB Connectivity

The CR100 can communicate with a host device through Bluetooth or USB. Bluetooth provides a convenient wireless connection for mobile POS applications, while USB can be used where a wired connection is preferred.

A typical mobile payment architecture can be structured as:

Payment Card → CR100 → Bluetooth/USB → Mobile Application → Payment Platform

In this configuration, the CR100 provides the card-reading interface while the application running on the host device provides the user interface and connects to the appropriate payment infrastructure.

The best connection method depends on the host hardware, application architecture, operating system, and deployment environment.

Compact Design for Portable Payment

One of the main advantages of the CR100 is its compact form factor. Measuring only 66 × 66 × 9.8 mm, the reader is designed for applications where portability and space efficiency are important.

The device uses a rechargeable 3.7V lithium polymer battery with a capacity greater than 250mAh and can be charged through Micro USB.

Its small footprint allows the reader to be carried alongside a smartphone or tablet without adding significant bulk to a mobile POS setup.

Security and Payment Data Protection

Security is a critical requirement for payment hardware. The CR100 specification includes multiple key management methods and cryptographic algorithms for payment-oriented applications.

Supported key management options include:

• DUKPT
• Fixed Key
• MK/SK

The listed cryptographic algorithms include:

• DES
• 3DES
• AES
• RSA
• SHA-256

These technologies provide security-related building blocks for payment solution development. The actual security architecture of a commercial deployment depends on the complete system, including the payment application, host device, processor, acquiring institution, transaction flow, and key-injection process.

For production payment projects, customers should confirm the exact security configuration, certification scope, and key-management requirements with the manufacturer and relevant payment partners.

EMV and Payment Certifications

The CR100 product specification lists several payment and regulatory certifications and qualifications.

These qualifications can be important when evaluating payment hardware for commercial deployment.

However, certification requirements vary according to country, payment scheme, processor, transaction architecture, and final software configuration. Certification information should therefore be verified against the exact production configuration required for the target market.

CR100 Mobile POS Terminal vs. Traditional POS Terminal

The CR100 follows a different design approach from a conventional countertop POS terminal. Instead of combining the payment reader, display, operating system, and payment application into one large device, the CR100 can work as a compact payment peripheral connected to another smart device.

The CR100 is particularly suitable when the software interface already exists on a smartphone, tablet, computer, or embedded host and a compact payment reader is required.

CR100 vs. NFC-Only Reader

An NFC-only reader may be sufficient for applications that only need contactless communication. However, payment projects may require both contact and contactless card interfaces.

For a project that needs both EMV chip card and contactless payment capabilities, a combined reader can simplify the hardware architecture.

Operating System and Application Integration

The product specification lists Android, iOS, Windows Phone 8, and Microsoft Windows compatibility, while the product description states that the device can be integrated into applications on iOS, Android, Windows, and Linux.

Because operating systems and mobile development requirements change over time, developers should confirm the current SDK, API, drivers, libraries, and supported OS versions before beginning a production integration.

The most important consideration for developers is not only operating system compatibility, but also the availability of the appropriate SDK and communication protocol for the intended application.

How the CR100 Works in a Mobile POS System

The CR100 is designed to operate as part of a larger payment solution rather than as a standalone payment-processing service.

A typical workflow can include the following steps:

1. Connect the Reader

The CR100 connects to a smartphone, tablet, computer, or other compatible host device using Bluetooth or USB.

2. Launch the Payment Application

The merchant opens a compatible POS or payment application on the host device.

3. Enter the Transaction

The application sends the transaction amount and required instructions to the payment workflow.

4. Present the Card

The customer inserts an EMV chip card or presents a compatible contactless card or NFC payment device.

5. Process the Transaction

The reader communicates the required card information to the host application according to the implemented payment architecture.

6. Complete the Payment

The payment application communicates with the appropriate payment infrastructure and completes the transaction.

This architecture allows the CR100 to serve as a compact payment interface while the software platform controls the broader customer and transaction experience.

Applications of the CR100

The CR100 can be considered for a variety of mobile and integrated payment applications.

Mobile Retail POS

Retail employees can use a smartphone or tablet together with the CR100 to support payment acceptance without relying on a fixed checkout terminal.
