Certain embodiments of the invention may be found in a method and system for multi-layer network interface controller operation. Specifically, for example, a method of conducting a wireless transaction is provided that includes initiating a wireless transaction using a short range wireless communication system of a portable electronic device. A sensor is supported by the support and is configured to sense the data being carried by reflected light from the data card. A second set of nodes, including nodes that intermingle data and control, are converted into bit-level nodes.
