Intro to Access Control: Prox & Smart Cards

What is a prox card? What is a smart card? How do they work? What do they do? What's the difference between them? Why is it important? If you've ever asked these questions, this video explains why prox and smart credentials are compared so often, and will help you understand terms like encryption, authentication, mutual authentication, interoperability, 125 KHz, 13.56 MHz, and more.

This was beautifully explained. Thank you for this video

Nice overview of Prox & Smart. I do not believe that the mag strip reader has a "magnet that activates the bits" on the magnetic stripe - it contains a read head like in a tape recorder. As the magnetically encoded bits pass the head, analog pulses of “0” or “1” are generated. Other than that minor issue I thought that the video was excellent.

What if I use 2 smart card 1 which have access to room and 1 doesn't have access to the room ..... And if I stick these both cards back to back and try to access the room what will happen in. That case

Nice video, but it would have been useful if they could elaborate on the authentication a bit more. The analogy is all well and good to paint the picture, but how does this actually work?

Maybe this video would help? kzbin.info/www/bejne/eIPTl4h_iLV4iq8

13.56MHz is actually more than 100 times as fast as 125kHz
