That was a really concise explanation of how RFID actually works! Not just a vague description, but showing how the chip is powered and how it transmits 👍

Actually the rfid chips are often from the Mifare series which is a product line of Nxp a european dutch company that creates automotive and rfid solutions. The mifare chips are the most famous and used in many products and cards that dont need any special security features like the chips in your bankcard or any card that should not be used by any other person. Also nxp has chips for secure rfid purposes which have a mcu in them and some security things. These mifare chips are kind of "dumb" and when powered just spit out the contents of the memory and dont have any mcu

Is it the same system in contactless bank cards? Are they basically an RFID tag as well?

Damn! You speak like Chinese with this accelerated video!

Can we use a coil over an RFID reader to get the interference caused by the key fob to get its data?
This would be an excellent method of stealing acces control data and get acces to almost any place, hence the safety concer

[yup]

Somebody please tell me what song this is??

There's also 13.56Mhz (HF) RFID Tag
Same frequency as credit cards when it has contact with credit card reader in stores

Any system waiting for a signal is highly fallible. This maybe the dumbest system I have ever witnessed.
