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.
It's a common mix-up (people barely differentiate between the terms anymore, though I'm surprised nobody in 2 hours mentioned it yet), basically RFID is (historically) an ID; a username. Like an ID field in a database. NFC is near-field communication: bidirectional. It does challenge-response and typically runs on hardened chips. But yeah people will call NFC chips RFID and RFID chips NFC all the time. Both are waterproof devices doing radio transmissions on wireless power and you can't tell them apart without using some equipment to try and read the chip type (even if most phones can do that nowadays), so I can understand the terminology generalisation
