The use of traveler's checks began to decline in the 1990s. This trend was mainly due to the development and popularization of more convenient and versatile payment methods such as credit cards and debit cards, as well as the rise of online banking and electronic payment systems. These new payment methods provided travelers with easier, faster, and safer ways to manage their funds while traveling, making traveler's checks less necessary. Additionally, with the improvement of the security and convenience of cash withdrawals from ATMs overseas, the use of traveler's checks has further diminished.
