OV-chipkaart decoding tools---------------------------The OV-chipkaart is the Dutch RFID-based public transport ticketing system.Each traveller needs an OV-chipkaart to travel. This package is an independentdecoder for the contents of these cards.It is very much a work in progress, but it's useful already for reading travelinformation. I hope that someday all this information will be fully open, andthat the card data will be accessible to their holders and the relevanttransport companies in a secure, transparent and privacy-respecting way.  ovc-decode    Show a human-readable print of the transactions on a                OV-chipkaart dump. To see station names instead of numbers,                you need to run stations/createdb.py first.  ovc-dump      Show a hexdump of an OV-chipkaart that fits on a large screen                if you find that I missed something in the output, let me know  dplay         Show text files consecutively on screen with differences                marked by color. Useful for tracing sequential dumps.Use, for example, like:                  for i in *.mfd; do ovc-dump $i >$i.dump; done; dplay *.dumpThanks to all who have helped with this.
