We have a potential requirement to produce a limited number of embossed PVC cards with magnetic encoding for an internal project.

Why not consider either keyfobs or credit-card size cards with embedded RFID tags ? Each RFID has a unique ID.

The cards have to interface with an existing system provided by an outside agency that is based on magnetic swipe technology. The potential project is internal but the environment is not.
