@arainda.speak: When you tap a contactlessly enabled credit card against a payment terminal, an RFID (Radio-Frequency Identification) and NFC (Near Field Communication) chip embedded in the card powers up via electromagnetic induction, generating a secure EMV tokenization process that instantly transmits a dynamic, single-use cryptogram over an encrypted radio channel to authorize the payment without exposing your actual primary account number (PAN).#ContactlessPayments #NFC #RFID #EMV #Tokenization #FinTech #CyberSecurity #PaymentSecurity #TapToPay #financialtechnology
And all that synchronization uses an unlike source to keep everyone lined up together: the GPS constellation. Using the ultra-accurate timekeeping from the GPS signal, all the devices stay synchronized and secure.

I work in Travel and so many clients get upset when their bank won't authorize a payment. But it's because most of us aren't making a 5 or 10 thousand dollar transaction. I tell them to call the number on the card so they can verify who they. 9 times out of 10 that's the issue.
