Help an oldtimer out with new tech

[acidbar]

I was in the game for a while, and got out once 101 started dying.. lost a lot of money trying to get emv sofware. Tried the nfc, had good luck one time, and bad luck every time after that.. I've been searching the forums, and I see the talk of 1 dip and 3 dip. So what I've gathered is 1 dip is a bigger chip. can anyone tell me exactly what type of card/chip that is? Do you leave the chip blank and use it, or do you short it out? and is the process the same if you use 3 dip, which I'm assuming is the jcop 21-36.
I appreciate any help or feedback you guys can give
