Payment Tokenization Shield (2D)

A stream of simulated card-payment packets flows across a real vending-machine payment pipeline — card reader, embedded controller, network link, payment processor — while an attacker's tap sits at a point you choose. Toggle tokenization and TLS encryption on and off and watch, packet by packet, whether the eavesdropper captures a usable raw card number, an unusable single-use token, or nothing but ciphertext. A lower inspector panel decodes exactly what byte pattern the tap point actually sees. Live readouts track the skim success rate and a PCI-DSS-style exposure score that reflects your overall security posture, independent of the attacker's current position — the same defense-in-depth logic that keeps a single compromised layer from turning into a full payment-data breach.
