b. Option 2: Simply reject any payment that triggers an alert, even though it may be legitimate. The Sender is given certainty about the status of the payment but will still be unable to make the payment next time. It may not be possible to give the Sender useful information about how to resolve the match; if they are in fact trying to avoid sanctions, this information could assist them to circumvent the screening software. This approach has been used with some existing cross-border instant payment systems but can lead to a significant percentage of payments being rejected, since many sanction screening software platforms will issue alerts on 10-15% of payments (of which over 90% are likely to be false matches). This approach is most appropriate for time-critical or point-of-sale payments, where the customer cannot leave the store before the payment completes.
