Overview

The Ingenico Link/2500 (similar to the iSMP4) is a lightweight, Wi-Fi-connected device that makes it easy to accept payments on the go, including MSR (magnetic stripe), EMV (chip), and NFC (contactless) payments. Connected directly to your point-of-sale via a Wi-Fi connection, the Link/2500 protects your transactions with a powerful combination of EMV technology and point-to-point encryption (P2PE), making each transaction secure and PCI compliant.

This article offers an overview of the Link/2500, as well as general information for ordering and setting up the device. For more detailed information for integrating the device with your CardPointe Integrated Terminal solution, see the CardPointe Integrated Terminal API.

Benefits and Features

By integrating the Link/2500 with your CardPointe Integrated Terminal P2PE solution, you can:

• Minimize your scope of PCI compliance with point-to-point encryption. Your CardPointe Integrated Terminal device encrypts sensitive card data and transmits it over over a secure HTTPS connection.
• Process payments using a Wi-Fi connection.
• Accept all payment types, including MSR (magnetic swipe), EMV (chip), and NFC (contactless).
• Easily add devices without making changes to your existing integrations.

Supported Connection Types

The Link/2500 requires a connection to a password-protected Wi-Fi network. Bluetooth and certificate-based authentication are not currently supported. See Secure Network Configuration Best Practices for information for creating or configuring your network.

The Link/2500 uses the WPA-PSK security protocol for authentication on your Wi-Fi network. WPA-PSK (Wi-Fi Protected Access II Pre-Shared Key) requires you to enter a network name (SSID) and password (WPA-PSK) to authenticate and connect the device to your network. See Configuring the Link/2500 Wi-Fi Settings for more information.

Secure Network Configuration Best-Practices 

Consider the following best practices for configuring your network for the Link/2500:

• Configure a DHCP IP address range to connect terminal devices to a dedicated subnet. Alternatively, use static IP addresses reserved for the devices.
• Configure a new WPA Wi-Fi (with password requirement) network for the new device subnet. Optionally, access to the network can be restricted to the specific MAC address or IP address of the device. For extended security, you can restrict the services or ports that are allowed to communicate over the network.
