Introduction

This is Elavon's EMV Implementation Guide for Point of Sale (POS). It contains generic EMV implementation requirements and guidelines for interfacing to Elavon, as well as the specific EMV implementation required to connect the different front ends/message specifications (Fusebox, viaConex, Encompass4, Converge, and ISO-8583).

Configurations supported

POS configurations

Multiple POS configurations are possible for both EMV and traditional Magnetic Stripe processing. In this section, the supported configurations (integrated and standalone) and their variations (fully integrated, partially integrated, and semi-integrated) are listed.

Integrated configurations

Integrated POS configurations are solutions where an external terminal is connected to an Electronic Cash Register (ECR), adding EMV contact and contactless functionalities to it.

Integrated solutions have different implementations, depending on the division of roles between the ECR and the Point of Sale:

Configuration Host connectivity Host message implementation EMV Kernel Contactless Kernel PCI scope
Fully integrated ECR ECR Terminal Terminal ECR and Terminal
Partially integrated ECR Terminal Terminal Terminal Terminal
Semi-integrated Terminal Terminal Terminal Terminal Terminal

note

The ECR can be removed from the PCI CDE scope if the terminal uses P2PE (for partially and semi-integrated configurations)

Figure 2 POS Architecture – Partially integrated

Figure 3 POS Architecture – Semi-integrated

Standalone configurations

Standalone POS configurations are solutions where the EMV logic (contact and contactless) and the acquirer host message implementation is managed within the terminal. In this configuration, there is no interaction with an ECR, if present.

Standalone implementations sometimes use an external PIN pad or contactless extension.

Transaction Authorization modes

Multiple authorization modes exist for processing transactions. The table below summarizes the different configurations, their meaning, and their support through Elavon.

Mode Designation Supported
Online Only All transactions are processed online. Yes
Offline with Online capabilities

This mode supports multiple scenarios:

Transactions authorized offline, based on specific risk management features.

Transactions are sent online for authorization based on terminal configuration and/or if they cannot be authorized offline.

Please note that this mode is different from STIP (Stand-In Processing).

Yes
Offline only All transactions are processed offline. This mode is used on specific scenarios (e.g: unattended cardholder activated –or UCAT) and is outside the scope of this document. No
