My Dell laptop seems to have a built-in smartcard reader but I could not find it neither in any of the hardware detection methods I've tried.

What could I do?

You mean the SD card reader on the front side and the SmartCard reader on the left side are from the same device?

Check if it is disabled from BIOS/UEFI.

Among all those options to enable / disable, I cannot find any for smartcard reader or fingerprint reader.

If you booted from SystemRescue check if they work. Then check what modules are loaded. You may want to boot the alternate kernel to get the latest.

charles17,

It may be on the i2c bus. The low bandwidth there is fine for something that works like a keyboard.

this may be of help http://natisbad.org/E4300/index.html; the 4300 and 6400 (6430) seem to be close cousins, looks like the basic bus is usb with a broadcom twist

Thanks for the links. The picture https://blog.g3rt.nl/images/20150717_dell_rfid_palmrest.jpg shows an icon also present on my laptop.
When I try with pcsc_scan I get:

Good catch. Did so and then it started waiting forever :-(

BTW: Device info from the manufacturer's support site:

FWIW, I couldn't get these to work on my e6510 either, in win7 or on linux. I think they're just busted. :lol:

Quote:
Out of the box, this reader is not PC/SC enabled. The contactless reader is only available through the CV chipset (Dell Credentials Vault), meaning that it will only work in PBA (Pre Boot Authentication), and when enrolling a contactless card through the Dell supported software (EmbassySuite/ControlPoint).


https://bibuweb.de/enable-rfid-reader-on-dell-laptops/

Quote:
For using the contactless reader in your own applications you have to disable the “CV Only Radio Mode”.
