PAX Full-Integration Implementation
As someone who has worked with PAX products for many years, I’m excited to share a review and summary of the latest PAX Full-Integration Implementation Guide, updated on October 15, 2024. This guide highlights the robust features, flexibility, and advanced encryption techniques offered by PAX technology for secure and seamless payment integrations. For developers or businesses using PAX terminals, this is an essential update.
This article provides an overview of the guide’s key features and examples, but developers can access the full document via the PAX Developer Portal for deeper technical details and full integration instructions.
🔍 Key Features and Command Examples from the Guide:
1. Multi-Method Transaction Handling
PAX’s BroadPOS P2PE/TermLink Application supports various transaction methods, including manual entry, swipe, and EMV chip. With the recent updates, the application now handles transactions even more efficiently, allowing for secure data capture via multiple methods—swipe, manual entry, or contactless.
InputAccountWithEMV EDCType = Transaction Type
ManualEntryFlag = 1 (enabled)
Amount = $100.00
2. Credit Sale Transaction
One of the most common transactions, a credit sale, is well-supported by PAX’s Full-Integration solution. Here’s how the AuthorizeCard command facilitates a secure credit sale:
AuthorizeCard
Amount = $100.00
TransactionType = CREDIT
CurrencyCode = "840" (USD)
EncryptionType = AES 256 DUKPT
3. Credit Return Transaction
In case of a return, PAX terminals handle this using a similar process. The AuthorizeCard command is modified to handle returns, ensuring secure reverse processing of funds:
AuthorizeCard
Amount = -$50.00
TransactionType = RETURN
CurrencyCode = "840" (USD)
4. Secure Data Transmission
With the new update, PAX has further strengthened its encryption protocols. By leveraging AES 256 DUKPT encryption, the terminal ensures that all sensitive data, such as PINs and account numbers, are securely transmitted. This keeps customer information safe, aligning with the latest security standards.
EncryptionType = AES 256 DUKPT
KeySlot = 1
PINAlgorithm = ISO9564_3
5. Simplified Command Integration
The document also introduces improvements in integration examples for developers using Java and Android. PAX continues to make it easier to initialize terminals, customize the UI, and retrieve key device information with just a few commands. The clear examples provided in the guide help speed up the integration process, even for complex setups.
Init.InitResponse initResponse = Init.init(context, commSetting);
String terminalModel = initResponse.getModelName();
boolean isTouchSupported = initResponse.isTouchScreen();
6. EMV and Contactless Payments
As contactless payments continue to rise, this update enhances the EMV Contactless Flow even further, ensuring seamless transactions. The guide walks developers through the steps for integrating contactless EMV, making it easier to handle secure, tap-and-go payments.

7. Customizable User Interface and Operations
PAX’s TermLink Manager continues to be a powerful tool for managing Android terminals. The new update offers improved flexibility in managing different communication types like Bluetooth, USB, and Ethernet. It also provides better UI customization capabilities, allowing businesses to create more personalized user experiences at checkout.
