Limitations
PIN numbers, expiry dates, or CVV codes are not redacted by this feature. Also, if the credit card pattern is different from the pattern mentioned above, it may not be filtered.
For example, if a user replaces a zero with the letter 'O' - the examples may be missed by the filter.
Enabling this feature only impacts future messages. The existing credit card numbers in conversations, already in queue, or already in historical transcripts are not redacted.
