During the Tech Discovery of the feature Free Refill Drinks (QR code), we identified two possible approaches of solution.

...

• SHA256. But this doesn’t use password. Double check with Paulo.

• MD5. But this is also a one-way algorithm. Double check with Paulo.

  • DynamoDB secrets table: rbi-account-secrets

    • rbi/<env>/<brand>/<country>/refill-machine

      • value: {"dispenser_password":"<>" }

  • Reference showing a intl-whitelabel-graphql call to retrieve secret: https://github.com/rbilabs/ctg-whitelabel-graphql/pull/1477

  • store id, transaction id, transaction datetime
