Preventing an unauthorized card transaction

An approach for preventing unauthorized card transactions is presented. An authorization record including an authorized geographic location and an authorized period of time is received from a travel reservation system (TRS) and stored to dynamically update a profile table that stores other authorization records. The authorization record identifies an itinerary specified by travel booking(s) purchased via the TRS using a debit or credit card. The itinerary specifies that the cardholder is scheduled to be in the authorized geographic location for the authorized period of time. In response to receiving a request for an authorization of a card transaction, a location and date associated with the card transaction are retrieved from the request. The card transaction is rejected based on a determination that the retrieved location is not within authorized geographic locations included in the stored authorization records that have authorized time periods that include the retrieved date.
