  * cyberJack RFID standard:

    62 x 95 x 13 mm

  * 0.332 enclosure:

    69 × 111 × 13 mm

It could be fun to replace the pin pad by a smaller one and create a
custom board. IOW it could be fun to create an open source card reader!

Did that in the past too. However, the “cyberJack RFID standard” needs
dedicated drivers while the Reiner SCT directly interfaces with
GnuPG. In particular with Termux on my rooted Android phone, I did not
get the cyberJack to work.

I understand, but that’s not my use-case. If someone wants to give it a
go, it should not be too hard to modify the current design. You can
start from the STL files if you don’t have Rhino3D (proprietary).
