The full sentence is
> External devices can be attached as card reader overlays, deep-inserts inside the magnetic stripe slot, those that fit in the EMV slot (chip reader) and those that wiretap the physical communication line.
I believe the "those that fit into the EMV slot" and "those that wiretap the physical communication line" are two different types.
A skimmer in the EMV slot can still skim the mag-stripe. Wiretapping the communication line is used when the ATM/Payment terminal uses poor security between it and what ever its connected too.
- bradknowles 8y agoExcept an insert into the chip reader slot isn't a full insert of the entire card, and so they're not going to get the full mag stripe. Now, if they don't need the full mag stripe, then you've got a problem. But I don't think that mechanism would work for most skimmers.
- Crosseye_Jack 8y agoSome of the card dip style readers do have a full card insert. Examples would be the in shop ATMs that prevent the card from being removed (so they can query the chip).
