How It Works

Supported Payment Methods

PingPongCheckout's in-person payment solution supports the following payment methods:

• Credit card payment Cash register processes credit card payments directly through physical POS devices, supporting multiple card types.
• QR code payment When your cash register has a rear screen that can display QR codes, payments can be completed by scanning codes.

Credit Card Payment

1. Interaction mode:

   • One request for both order creation and payment
   • Customer swipes card directly on POS device
   • Payment result returns to cash register system

2. Device dependency:

   • Strongly dependent on physical POS devices
   • Must pass device identification parameters: deviceSn, deviceModel, cashierDeviceId
   • Payment requests are forwarded to specified POS device for execution

3. Data characteristics:

   • Returns detailed card transaction information (cardTransinfo)
   • Includes acquiring bank information, card number (usually masked), cardholder information, etc.
   • Supports queries to obtain more complete transaction details

4. Refund characteristics:

   • Refunds must be executed through the original POS device
   • Refund requests must include device information
   • Refund process is relatively synchronous, but still requires queries to confirm final status

QR Code Payment

1. Interaction mode:

   • Asynchronous processing flow, divided into two phases: QR code acquisition and payment confirmation
   • System generates QR code, customer uses mobile device to scan and pay
   • Payment result requires waiting for user to complete payment operation

2. Device dependency:

   • Not dependent on POS hardware devices
   • Only requires cash register terminal to display QR code
   • Payment completed on user's mobile device

3. Data characteristics:

   • Returns QR code information: qrCode, qrUrl, qrCodeExpired
   • Does not include card transaction information
   • Data structure is relatively simple
