12:38 <makilkaa> Does anyone know where the encryption chip might be situated within this square reader? https://imgur.com/a/38YMa

13:48 <wpwrak> makilkaa: my guess would be one of the two larger chips, either the one near the center or the one above it. you may want to take a picture that zooms in on the area marked with 27/17 and has the light at an angle that makes the package markings readable. (such photos are very sensive to finding the right angle - even a few degrees can make all the difference between completely invisible markings and clearly readable ones.)

13:48 <wpwrak> not sure if the large chip even has markings, though

21:02 <DocScrutinizer05> sounds like whitequark :-)

21:03 <DocScrutinizer05> or A.Zonenberg though the name clearly doesn't match there
