Mastercard is launching a tool to help banks spot and cut off transactions from crypto exchanges that are susceptable to fraud, according to CNBC. The new system is called Crypto Secure -- and apparently uses "sophisticated" artificial intelligence algorithms to gauge how risky interacting with a particular trading platform is. It comes over a year after Mastercard aquired CipherTrace. Banks and fellow card issuers are set to be given a color-coded dashboard that shows whether incoming transactions are low or high risk.                                                                   While Crypto Secure won't turn down transactions on a merchant's behalf, it's designed to help them make informed decisions. This tool could boost adoption of crypto as a payment method among businesses.
