A transaction data capture system comprises a data capture interface, a portable data capture module (herein, the “PDCM”), and a data transfer interface. Transaction data from an electronic transaction device that would normally be directed to a paper printer is sent to the data capture interface and written to the PDCM. A data transfer interface formats the captured and stored transaction data for import into a software application operating on a computing device. The software application is selectable by a user of the computing device.
