Naming[edit]

This has just been re-named to Opus (smart card), which I regard as a fairly bad name on the grounds that it's not a smart card technology, but the name of a roll-out project within a public transport network. Following the example of Oyster card, how about simply Opus card?

It was worse, with Smart Card capitalized for some cryptic reason; but I've got no objection to your idea (or maybe Opus (card)?) --Orange Mike | Talk 16:32, 22 July 2008 (UTC)[reply]

I moved it to OPUS card (like the vast majority of the transit cards). I capitalized the name because that is how it is referred to on the official site. MTLskyline (talk) 03:54, 7 August 2008 (UTC)[reply]

Technology[edit]

What technology does this card use? There ought to be some explanation of this (and the implications for users) and ideally links to ext. refs on the tech and comparisons with other cities using the same tech. It's very rare today that such a system uses a wholly new card format.

If, as one of the refs suggests, this is the same tech as the London Oyster card, then the Dutch vulnerabilities are of serious notability. This ref ought to be in here "Oyster card hack to be published". BBC news.

The old MIFARE classics are cracked, not the new MIFAREs. STM is buying their cards from Oberthur CS and they're all based off the new MIFARE cards. http://www.oberthurcs.com/getpage.aspx?id=91 206.248.152.178 (talk) 07:11, 18 October 2008 (UTC)jaime—Preceding unsigned comment added by 206.248.152.178 (talk) 07:09, 18 October 2008 (UTC)[reply]

BIXI is now accepting OPUS. Leaving this here until I sort out how to put it properly in the article, don't have time at the instant. BIXI Montreal^[1] | Summer 2017

Stored value[edit]

The first sentence says it is a "stored-value smart card" and the last sentence under Fares mentions "its lack of stored-value capability". One of those is wrong. JoeBrennan (talk) 18:48, 29 April 2019 (UTC)[reply]

They are smart cards that hold value, but not money as they hold individual tickets. It does not need network access for the fares to be used. In a sense, it does hold a monetary value in terms of fares, but it does not function in the same way as cities with funds on their transit cards.

I believe it might make sense to not call it a store-value smart card. NetOrange (talk) 05:09, 15 November 2023 (UTC)[reply]

Name of card[edit]

Where does the name "OPUS" come from? Is it an acronym? If so, what does it stand for? ESP (talk) 17:44, 7 November 2021 (UTC)[reply]

OK, my kids just explained it to me. Carte OPUS is a pun on carte au puce, the French word for a card with a chip in it. I'll find a reference and add it. ESP (talk) 17:48, 7 November 2021 (UTC)[reply]
