Payment systems · AI security
Learn payment security by reading real transactions
A research platform built on captured EMV, NFC and magstripe traffic — sanitised, decoded, and explained byte by byte. From your first APDU to original research.
Four levels, one path
Each level has its own entry assumption and its own exit test.
Level 1
Foundations
“I know security. I don't know payments.”
Level 2
Practitioner
“I can read a trace. Now interpret it.”
Level 3
Operator
“Show me the attack, end to end.”
Level 4
Researcher
“I want to find something new.”
About this data
These captures were recorded from real cards and then sanitised. Card numbers sit on published test ranges, track data was rebuilt to match, and certificates were replaced. No live cardholder data is served here.
