Federal Communications CommissionDevices emitting radio frequency signals must be declared at the FCC to be sold in the USA (or something like that). Smart card readers are such devices since they use electricity.
I let you read the wikipedia page to know more about the FCC.
Search engineThe Office of Engineering and Technology (part of the FCC) provides a search engine at Equipment Authorization Search.
Example: Gemalto MESPROXDUBI searched for all the Gemalto devices. The list contains 381 results.
I found the MESPROXDUB also known as IDBridge CL300 (previously known as Prox-DU) smart card reader. I have it in my own list at Gemalto Prox Dual USB PC Link Reader.
The result of the search is a list:

For a strange reason it is not possible to directly access the referenced PDF documents. You will get a "You are not authorized to access this page." if you click on the links in the table above. You need to get them from the real result page itself.
PicturesWhat is interesting for a hardware hacker are the "Internal Photos". This is called "hardware p0rn".
You can search "hardware p0rn" in Google. Maybe some pictures from Google are NSFW. There is also a tumblr dedicated to hardware porn with nice (and safe) pictures.
