Accenture built the PRESTO system (payment card for Toronto transit) and of course they store plaintext passwords (https://www.reddit.com/r/toronto/comments/1subk4/presto_card...)

And from personal experience:
Jesus wept, Presto was a truly awful rollout, not least of which was the awful UX/UI of the terminals at the stations.
Oh, and of course, in 2021, you still cannot tap-to-pay using NFC on your phone. Now, that may not be Accenture’s fault; that could obviously and easily be the failure of sclerotic Canadian bureaucracy. But I would not be surprised if the back end simply does not support such a thing without another $50 million in consulting fees.
