e-Amusement Card Convert
A command-line utility for converting between card numbers written on the back of an e-Amusement card and the card ID stored in the RFID on the card.
This utility is a port of the card convert utility originally written in python by @DragonMinded.
Usage
Run it like ./eamusecardconvert <card-id>
. <card-id>
can be either the 16-character card ID stored in the RFID on the e-Amusement card, or the 16-character card number as shown on the back of the e-Amusement card. Whichever value is supplied, the resulting output will be the conversion to the other. Inputs will be sanitized, so you can feed card ID and back-of-card numbers with or without spaces, with or without hyphens, and you can also mix up 1
and I
as well as O
and 0
. Both old-style and newer FeliCa style e-Amusement cards are supported.
