| 1 | Card and Contactless Payment Acceptance | Support EMV chip cards, contactless cards, and NFC mobile wallets used in the target markets. | EMV chip technology helps authenticate card transactions, while NFC contactless payments operate at 13.56 MHz. | Request payment-scheme certification, test chip-and-PIN transactions, and confirm contactless acceptance limits by country. |
| 2 | Payment Security | Choose a terminal with PCI PTS approval, secure key management, encrypted communication, and tamper detection. | PCI PIN Transaction Security requirements address device protection, PIN security, and resistance to physical attacks. TLS 1.2 or later is commonly required for secure data transmission. | Check the current PCI approval status, supported encryption method, remote-key-injection process, and tamper-response behavior. |
| 3 | Connectivity and Network Resilience | Prefer multiple connection options: Wi-Fi, cellular data, Ethernet, and Bluetooth, with automatic failover where available. | 4G LTE provides broader geographic coverage than older 2G or 3G networks in many markets, but network availability still varies by country and operator. | Confirm supported cellular bands, SIM or eSIM configuration, offline transaction rules, roaming capability, and reconnection behavior. |
| 4 | Currency and Localization Support | Support the required currencies, local decimal rules, date formats, languages, tax displays, and receipt formats. | ISO 4217 defines three-letter currency codes, such as USD, EUR, GBP, and JPY. Currency minor units differ; for example, JPY normally uses zero decimal places while EUR uses two. | Test currency rounding, refunds, tips, tax calculations, receipt language, and settlement currency for every intended market. |
| 5 | Transaction Speed and Reliability | Target a smooth customer experience with clear prompts, fast authorization, durable hardware, and reliable battery performance. | Actual authorization time depends on the acquirer, network quality, issuer response, transaction type, and risk checks; supplier claims should therefore be validated in field tests. | Measure completed transactions in busy periods, test low-signal conditions, review battery endurance, and check failed-payment recovery steps. |
| 6 | Integration and Management | Select a terminal compatible with the required POS software, payment gateway, APIs, inventory tools, and remote device management. | Common integration methods include REST APIs, Android-based applications, cloud dashboards, and standardized receipt or transaction exports. | Confirm API documentation, sandbox access, software-update controls, role-based permissions, audit logs, and data-export formats. |
| 7 | Total Cost and Local Support | Compare hardware, payment processing, connectivity, currency conversion, maintenance, replacement, and deployment costs. | The total cost of ownership can exceed the purchase price when recurring connectivity fees, chargebacks, repairs, software subscriptions, and cross-border settlement charges are included. | Request a country-by-country fee schedule, warranty terms, spare-unit policy, service-level targets, training plan, and local-language support details. |
