Patent attributes
A method and an apparatus are provided for a universally operable Radio Frequency Identification (RFID) tag reader base unit. An RFID base unit is provided that can communicate with at least two different types of RFID tags, one at a time, that are commercially available as well as communicate with data collecting entities using any of at least two communication standards. The reader comprises a microprocessor (microcontroller) portion having at least one set of plug-in connectors. The reader then operates in different operational logic processes in accordance with the types and parameters of attached plug-in modules. The plug-in modules will typically comprise RF frequency modules for communicating with the RIFD tags as well as a communication standard model for communicating with a computer network. Additionally, the plug-in modules contain memory that contains data and code used by the microprocessor in performing the operations obtainable by specific types of plug-in modules. If upgrading of the operating system is required, such upgrading can be accomplished through the use of an associated port such as a microcontroller interface port, a memory stick slot or using a computer in conjunction with a communication module.
