Flipper Zero is one of the handiest little pieces of tech I’ve ever owned. Being able to copy RFID keys is occasionally fantastically useful.

Is... that possible? I thought the whole point is that those were a challenge-response specifically to avoid ever them disclosing over the air the material necessary to impersonate one.

Keyfobs absolutely should use a secure challenge-response protocol in order to prevent cloning. Unfortunately, it's extremely common for RFID devices to simply use the tag ID which is trivially cloneable. Many of the systems that make some attempt at security still fail by using a broken protocol or a flawed implementation.

Is this something you do often? I could see a few use cases and also for copying garage keys. But I don't think I would use it enough to justify the investment

This is not a rational purchase - most of the rule breaking done with the zero is for fun or convenience, rather than being truly illegal.

It used to be more fun before the hotels started handing out NFC unlocks with your phone.

Still, being able to send each other a key for a hotel room on Signal is a nice trick if you are traveling with a sufficiently tech savvy group of people.

Why can't something be "done"?

Was just reading something along those lines:

> We need to normalize declaring software as finished. Not everything needs continuous updates to function. In fact, a minority of software needs this. Most software works as it is written. The code does not run out of date. I want more projects that are actually just finished, without the need to be continuously mutated and complexified ad infinitum.

Nope! Only occasionally. But it’s handy on those occasions.
