Contactless Payment Terminals: Compatibility, Setup, and Failed Taps Working record | Updated October 3, 2026 Guide: https://yenra.com/card-terminal/ Purpose: Check terminal, point-of-sale and processor compatibility and distinguish a failed contactless read from a declined or uncertain payment. Instructions 1. Save a separate copy for each site, job or configuration. Use test aliases where records concern people or payments. 2. Fill each field with a result and its evidence reference. Mark unknown items UNRESOLVED; do not infer a pass. 3. Record the configuration, document revision and date behind each result. Keep credentials and sensitive records in approved systems rather than this worksheet. 4. Assign unresolved items an owner and next action. Sign off only within the scope actually verified. 5. Recheck affected fields after the configuration, supplier or requirements change. Evaluation name: Date and reviewer: Scope and intended decision: 1. Terminal model/identifier and software: Evidence/reference and result: 2. POS product/version: Evidence/reference and result: 3. Processor/acquirer confirmation reference: Evidence/reference and result: 4. Supported methods and currencies: Evidence/reference and result: 5. Payment-to-sale reference mapping: Evidence/reference and result: 6. Approved testing procedure: Evidence/reference and result: 7. Tap/decline/cancellation/refund results: Evidence/reference and result: 8. Uncertain result status-check procedure: Evidence/reference and result: 9. Duplicate-request test result: Evidence/reference and result: 10. Outage and offline-mode owner: Evidence/reference and result: 11. Reconciliation and staff training signoff: Evidence/reference and result: Illustrative example from the guide (fictional, not a test result) Invented example: the terminal finishes before the till recovers A fictional sale is for $42.00. The customer taps and the till loses its connection before showing a result. Staff retain the original sale and payment reference, then check the provider’s transaction status. If the payment is confirmed approved, they reconcile that payment to the sale instead of collecting another $42.00. If status remains unresolved, the designated support procedure owns the next decision.
