https://github.com/metrodroid/metrodroid/wiki/Go-%28SEQ%29 mentions that Go Explore (among others) have not yet been analysed as no samples have been acquired.

I'm happy to share the dump of a 2017 Gold Coast Go Explore card that was used in 2019 to any interested devs (AK series EV1 card with hard prng). Of interest the card is noticeably thinner than regular Go cards, which I guess makes sense to save costs given their more limited lifespan.

Also of interest, it mentions only AK and GD series cards, but I have in my collection a regular Go card of AB series, date on the card is 2013 and looks to be an original mifare classic with weak PRNG

Samples are always welcome (my github username) @ gmail.com; and if it's possible to get photos of what the TVM says, this helps too – then we can get more Stop IDs and confirm any guesses.

That part of the wiki (and probably the website) is out of date... both phcoder and I have since acquired a couple of samples of the "Event" and "Explore" cards, and attempted to parse the travel passes (which looks similar to Los Angeles cards).

I've got a couple of other random Go cards of various types (transit litter) in my backlog to go through, but they have hardened PRNGs.

The description of card series might be out of date as well, as I've since seen a card with a printed (not engraved) serial number with hard PRNG, and we could also use some of the graphics (tram icon, QLD Government logo) to date them :)

What does your 2013 card look/feel like? Does it have a printed serial number?
