Each bank’s fraud department has protocols in place that are immediately activated when fraud is being detected. Knowing these controls can help you protect your business.
If issuers want to protect themselves, they can decide to block transactions that come from other countries, including the USA (country with the highest fraud rate), so that cardholders cannot make withdrawals or purchases with cards that have a magnetic strip/PIN until they contact their bank and let them know they are traveling outside Puerto Rico. This measure can be taken after a portfolio analysis is conducted because all banks have clients living in other countries that regularly make transactions from abroad. This proactive control can have a negative impact on cardholders if their card is blocked.
