A BIC is eight or eleven characters of unremarkable capitals, which is exactly what makes naive detection useless. Redactly requires a digit or an explicit SWIFT/BIC cue nearby.

## How Redactly detects SWIFT/BIC codes

- Matched by regex for four letters, a country code, a location code, and an optional branch code.
- Rejected unless the value contains a digit or a SWIFT/BIC cue appears within the preceding characters.
- This is what stops words like CONFIDENTIAL or PARTICULARS being redacted as banks.

## Why redact SWIFT/BIC codes?

Payment instructions pasted into support threads expose the routing path for a customer's funds.

## Example request

```bash
curl -X POST https://api.bitbanger.in/v1/redact \
  -H "X-API-Key: rdct_your_key_here" \
  -H "Content-Type: application/json" \
  -d '{"text": "Intermediary bank BIC DEUTDEFFXXX, charges SHA.", "style": "replace"}'
```

## FAQ

**Does Redactly redact SWIFT/BIC codes automatically?**

Yes. Send text to the API and every detected type is redacted, including SWIFT/BIC codes. To redact only this type, pass the value financial.swift_bic in the entities filter. No training or configuration is required.

**What happens to SWIFT/BIC codes after redaction?**

With style set to replace, each match becomes [financial.swift_bic] — the entity type in square brackets. Setting style to mask replaces every character with a block character, and remove deletes the span entirely.
