Only the xEM part of the implant can emulate different chips. It’s only one at a time. Typically you clone a card to the chip and part of the cloning process is telling the chip what mode to be in… Once it’s set that’s it until you change it. it’s not an “on the fly” thing.
For the most part, EM mode and HID mode are by far the most common modes. Indala is another mode.
