Abstract
Methods and systems related to near field communication (NFC) front ends for point of sale terminals are disclosed. One point of sale system includes an NFC front end communicatively coupled to an antenna, a discrete microcontroller (DM) communicatively coupled thereto, and an applications microprocessor (AP) communicatively coupled to the DM. The DM stores a first software stack for a first NFC protocol, a second software stack for a second NFC protocol, and instructions to process a digitized NFC signal from the NFC front end with the first software stack. The AP stores instructions to instantiate an operating system for the point of sale system, instantiate a master NFC service, and transmit a remote procedure call from the master NFC service to the DM to switch between the first software stack and the second software stack.
