Other cars require you to push a button to lock/unlock. Tesla senses where your phone is and when it is sufficiently far away, it locks (if the correct options are set up in the car). That is a big difference.
The keycard has an RFID chip in it. It uses NFC (near field communication) to lock/unlock the car. I carry my card in my wallet at all times as a backup key.
I also have NFC on my phone and can use it as a keycard.
If you walk away from the car without the phone and with the card, it will not lock. You must present the card to the terminal in the B-pillar. If you unlock the car with the keycard, and walk away with the phone it will lock. If you have no phone it will not lock or unlock except with the card. I would never leave my phone in my car anyway just for security.
