The present disclosure provides methods and systems for implementing plug and play (PnP) support for a peripheral point of sale (POS) device. In an example of a method, a PnP control interface is installed above a universal point of sale (UPOS) software interface. A disconnection of a peripheral POS device is detected and a UPOS software state for the peripheral POS device is stored. The PnP control interface is used to perform finalization method on a list of active peripheral POS devices in a Logical Device Name (LDN) library and an outstanding process for the peripheral POS device is terminated.
