How card data tokenization works
Tokenizing data

Fast verification
Standard verification is done in 23 steps, so less load, and less hassle

- Separate log records
- Regular review

If unusual login is detected on the same device, the session is refreshed and the account is not kept open
If cookies are turned off, some parts may load slowly, but the core data is not visible, because account control remains separate
Crypto wallet data and risk reduction
