$SMME The SmartMetric Crypto Card solution has its own crypto key secure element inside the card protected by firewalled encryption. This allows for the safe storage on the card of encrypted crypto keys in a highly functional manner.

SmartMetric has built inside its crypto payments card significant memory along with a crypto engine inside a secure element chip separate from the secure element used to perform credit and debit card transactions. By having two separated firewalled secure elements we are able to provide a much higher security than current card architecture provides while also providing greater memory and added encryption power. https://finance.yahoo.com/news/smartmetric-ma...00356.html
