Tokenization
Replacing sensitive data with non-sensitive tokens.
Why it matters
Tokenization matters because it directly affects payment security, data minimization, authorization reliability, PCI scope, and how teams explain the boundary between card infrastructure and digital-asset infrastructure.
How it works
Operationally, the original credential is collected, exchanged for a token, stored or transmitted as the safer reference, and mapped back only by the authorized token service or payment infrastructure when the transaction requires it.
Risks and pitfalls
The main risk is using tokenization as a generic security label while ignoring who issues the token, what domain it is valid in, how detokenization is controlled, and whether the token reduces or merely relocates operational risk.
Regional notes
Across BIST, MOEX, and global contexts, terminology should separate card-payment tokenization from capital-market tokenization and crypto asset representation, because regulatory duties, custody assumptions, and settlement flows differ.
