Questions and answers

Is the TrustSEC FIDO2 Smartcard worth it over a YubiKey?
It covers the same FIDO2 and U2F basics on a certified Infineon chip. Choose it if you want a card for contactless or badge-style use; a YubiKey is smaller and has more consumer-friendly tooling.
Does it work with Google, Microsoft and GitHub accounts?
Yes. Any service that supports FIDO2 or U2F security keys should accept it, including Google, Microsoft and GitHub. Check that your chosen version includes the interface you need, such as NFC for phones.
Do I need a special reader for the contact version?
The contact/contactless version needs a smartcard reader or a phone with NFC. The USB-A version plugs directly into a computer and needs no reader.
What is included in the box?
The listing does not specify box contents. Expect the card itself; a reader or lanyard may not be included, so confirm with the seller before ordering.
When is the best time to buy it?
No price history was provided, so there is no reliable cheapest period to point to. Compare current store prices before buying.
