Systems and techniques for coordinating data received from radio frequency identification (RFID) tags and additional data input devices. An RFID reader communicates with RFID tags and also receives data from additional input devices that may be correlated with the RFID data. The reader correlates information received from various data sources. Correlation may include validation of RFID data with corresponding data received from other devices. Once data has been received and correlation has been performed, transaction entries are prepared based on the correlated and validated data. Transaction entries may be passed to a data station for processing or logging, or to allow the data station to indicate appropriate actions to be taken. Appropriate software modules used by the reader are changed in response to changes to data input devices or the data station used with the reader.
