GoTrust’s card form FIDO2 product. The dedicated product page has been retired and no current vendor SKU is sold.
IdemCard
The IdemCard’s dedicated product page on gotrustid.com no longer resolves as of April 2026. The product appears to have been retired in favour of GoTrust’s Idem Key family, which now has dedicated Idem Key, Idem Key Plus, and Idem Key Mini variants. Existing IdemCards in service continue to work, and second hand units are still available, so the writeup below is preserved for reference.
GoTrust’s IdemCard is a unique offering. For those who need SmartCard access, this can definitely be an option.
Paired with their IdemKey, the IdemCard makes a great one-two punch solution for securing accounts. The hitch here is that you’ll need to either have a laptop with bluetooth or be able to set up the card with a phone. This means that if you’re using Google’s 2FA, you’ll need to do some legwork. HowToGeek has a comprehensive tutorial on setting up Bluetooth tokens using a phone.
Under Windows, it appears that the Windows Hello FIDO2 interface will recognize this via the SmartCard interface, if you have a reader. Under certain circumstances, Windows may require you to remove and re-insert the card to make sure that you’re human. This behavior has been confirmed to work with Microsoft Edge as of Februrary 2022.
Windows does require a short amount of setup to register the card with Windows Hello Preliminary evidence also says that this potentially disables or changes NFC compatibility. This was reported to @indrora by a friend.
Battery life
Claimed: About 2 months. Included in the box is a USB charger. A standard SmartCard reader will, also, charge it.

TrustID claims this will work with “everything except FeLiCa” which is a bold claim to make.
