Local Footprint Terminal Solution

A non-embedded, or local footprint, terminal solution is often referred to as a DLL based solution. This type of terminal involves being a slave controlled by a master program. The controller is typically a Dynamic Link Library (DLL) mini-program that is installed on a workstation. This approach was developed at a time when terminals did not have a dedicated Ethernet connection, but were controlled by serial port.
The benefits of this type of solution:

  • Wide acceptance in the industry
  • Wide availability, and
  • Non-maker components are generally not required.

The drawbacks of a local footprint solution include:

  • PA-DSS requirement – Cardholder information flows through a merchant network, so Payment Application Data Security Standard (PA-DSS) certification may be necessary to deploy the terminal solution to an environment that is already PCI compliant. Future software changes then require expensive and complicated recertification.
  • Point-to-point encryption problems – Implementing authentic P2PE requires complex and expensive PA-DSS certification on the encrypting code. There is controversy between PCI auditors over whether non-embedded solutions are certifiable for removing POS systems from the scope of PCI compliance.
  • Updates can be complicated and tricky – Code that is a component of a primary application is easily updated as part of the main application. Updating unbundled code requires a procedure or management system to update.

There may also be additional costs associated with using components requiring licensing. The solution may also be linked to a particular operating system and support may not be available for other systems.
