> In this context, crypto = cryptocurrency, because MasterCard is a major fintech company. The context is obvious. I, for one, was confused while taking the context into account (but having no idea what CipherTrace does): fintech companies, and especially those dealing with bank cards, are among the most common examples of encryption and authentication usage; I think it's even common to say "that's how your bank card transfers are secured" when explaining the usage of asymmetric cryptography to laypeople. Though the possibilities I've imagined were rather silly: e.g., some custom cryptographic hardware, for either efficiency or doing something fancy with quantum cryptography. Upon skimming the article, I'm not sure if the reality is much less silly, but the brief confusion happened either way.
