Because of the record of purchases for the user from a previous year, the sudden
influx in purchases would be flagged as anomalies given the context. Such a cluster of
purchases might be normal for Black Friday or before Christmas, but in any other month
without a major holiday it might look out of place. In this case, your person might be
contacted by the corresponding officials to confirm if they made the purchase or not.
Some companies might even flag purchases that follow normal societal trends. What
if that TV wasn’t really bought by your person on Black Friday? In that case, company
software can ask the client directly through a phone app, for example, whether or not
he/she actually bought the item in question, allowing for some additional protection
against fraudulent purchases.
