I was prepared to disagree with you, but I now have the same interpretation you have. Durable medium can be email - but the example seems a little fuzzy, for instance a durable medium is definitely when the email is stored on a HDD on a customer device. But is it still durable medium if the email only exists in a webmail? Probably yes, but maybe no. So the conservative approach would be to send paper for some things. (Or in this case, stupidly, USB devices. Banks, don't do that, please.)

Ramble Edit: it's unfortunate IMHO that there is no "read only" medium anymore. Not sure what it would look like now when USB-C is taking over the world, and that ship probably sailed, but it would be really cool and useful to have the option of a "data only" USB.

Maybe computers could have one USB port marked as "ROM". Or a switch or LED symbol indicating "ROM safe" mode.

When using such a ROM port, anything USB inserted there would only look like a DVD reader. A USB drive would get its files "mirrored" into a virtual ISO filesystem. Any other devices, such as keyboards etc would be just ignored and not connected to at all.

> There's an EU law demanding such documents to be delivered on a "durable medium". Some banks and financial institutions may have a strange approach to those, even though email attachments seem to be enough for others.

Even the (*-grand)parent never said the law actually says it can't be an email attachment, they said companies seem to interpret it that way. Which would not be surprising in the least. Then someone said they've never heard of any such law, and I pointed out that it exists.

I'm not sure who you're arguing with but it isn't me or in fact any of the people in this thread.

Putting aside what? Go back and read what the GP actually said, and what the parent comment (yours) actually said as well. All I was pointing out is that there is in fact such a law (requiring a durable medium), because you said you had never heard of such a law.

Sheesh, reading comprehension, please. That or stop moving the goalposts
