I have used it the presently.
Have you got an app or software that works with the card reader?
Presumably it can at least read your name, and id number, and birthdate.
I vaguely remember people here reading passport information.
I'm still intrigued by those top contacts. Are they just a decorative label, or does something actually connect via those contacts?
Also, is the connection to the app via USB cable, or wireless?
Does the card reader have a battery? How does it get power?
