Thanks. Sorry these are what credit cards use? Or recommend for wallet use? They have a better track record than Atecc?
ST32 means STM32 I assume?
Funny because as opposed to dedicated secure elements these are general purpose programmable microcontrollers with cryptography just one of the features they offer. You even have to BYO cryptographic library in the case of STM32. intuitively, that would make them more vulnerable? Larger attack surface?
SmartMX3 and Tegrion say "EMV payments" on their product page that sounds promising. This application has had much broader and longer exposure than e.g. Yubikeys/FIDO so if they have stood that test of time then that speaks for them.
I've been looking into SE050 as Atecc replacements might look into them further against this background. I'm still unhappy with the state of open source FIDO keys (too expensive/too complicated).
