Again, look up the definition of computer.
It processes the information on the card. It doesn’t matter HOW it does it, mechanically or otherwise.
No. There is no computation. If there is no computation it is not a computer. If it’s not a computer it’s not using a computer language. It also cannot be said to be “processing” in the same way your computer processes. Unless you think your food processor is computing the vegetable dip you put in it.
