CSG Payments' tap-to-pay solution uses NFC-enabled terminals that are part of the CSG Payments Protect program, which includes PCI-validated point-to-point encryption (P2PE). Card data is encrypted from the moment the card or device is tapped, rendering it unreadable if intercepted. This eliminates the risk of cardholder data exposure at the point of interaction.

CSG Payments supports tap-to-pay through its certified terminal lineup, including the V400C Plus, which supports NFC/contactless payments. The Device Handler software enables integration with existing web and desktop POS applications. While CSG Payments' terminals are recommended for P2PE compliance, the platform's API and Device Handler support flexible integration with compatible third-party hardware setups.

CSG Payments' Device Handler software connects NFC-enabled terminals to existing web or desktop POS applications via API, enabling tap-to-pay within the merchant's current checkout workflow. For mobile scenarios, the eDynamo card reader connects via Bluetooth, supporting tap and chip payments from a mobile device without requiring a traditional countertop terminal setup.

Tap-to-pay transactions are processed in real time through CSG Payments' payment gateway, with authorization typically completing in under a second. Customers simply tap their contactless card or mobile wallet against the terminal, receive an immediate approval, and the transaction is complete with no PIN or signature required for eligible amounts.

CSG Payments' terminals include various connectivity options including Ethernet and Wi-Fi. Specific offline or store-and-forward functionality for tap-to-pay in low-connectivity environments is not fully detailed in available documentation. For environments with unreliable connectivity, it is recommended to discuss terminal capabilities and fallback options directly with the CSG Payments team during implementation planning.
