USB Mode Integration
This feature is currently under development and is expected to be available in an upcoming release. Thank you for your interest and patience!
Introduction
POS application need to push order to the payment terminal in real time. They can be connected by USB cable. POS application send serial communication commands to WiseCashier ECRHub service to process payment request.
In USB cable mode, the ECR integration solution can only supports windows OS(7 version above)
The following is the process diagram:
- POS application sends order info (such as: order number, total amount etc. ) by usb serial communication command to WiseCashier application.
- The checkout module of WiseCashier collects the bank card information/mobile wallet user credentials and processes it securely, then merges it and order information in the transaction data, and sends the payment request to payment gateway/acquire/processor/bank.
- Payment gateway/acquire/processor/bank responses result to WiseCashier application.
- WiseCashier send transaction result to POS application by serial communication command, and display payment result on the screen.
Development Guidelines
1. Obtain Payment Parameters
Before starting the integration, you need to make some preparations, the most important of which is to obtain the payment parameters required for the integration. You need to contact your project support personnel to activate payment, and the main matters are as follows:
- Register merchant stores and other information
- Purchase payment terminals and binding
- Apply to activate payment methods and sign business cooperation agreements
- Register for application development and obtain an application development app_id
- Activate payment terminal(if bank card payment is required)
Please refer to the Payment gateway integration guide.
2. Connect POS to Terminal
Connect your POS device and payment terminal using the accessory USB cable that comes with the purchase of the payment terminal, ensuring the correct and stable connection of the line.

5. Access Our APIs
Integration with WiseCashier-SDK
We provide a Rapid integration with WiseCashier-SDK under local network. Currently, the SDK supports the following two programming languages
We recommend developers to use WiseCashier-SDK which secondary packages the communication protocol layer. SDK can help developers quickly complete application payment integration. In addition, we also provide Sample Code , and you can obtain their source code and latest version information through our GitHub.
2. Integration with APIs
If the above SDK cannot meet your needs, or if you need deeper control over product details, you can refer to our API specifications and write your own code.
