Diners Club Launches Official App Service "HISTORY" on April 1, Engraving the Journey with Members in Jewels

Sumitomo Mitsui Trust Club Co., Ltd. (President: Nobuaki Yamaguchi), which issues Diners Club cards, has launched "HISTORY", an official app service that records the journey with members by likening it to jewels, starting April 1, 2026.

This service was born in response to voices from members who have patronized Diners Club for many years, saying, "I would like to feel even more joy in continuing to hold the card." Aimed at deepening the relationship with members, it is a unique Diners Club service that visualizes the journey with the member itself, such as the number of years of contract and card usage, in the beautiful form of "jewels", and delivers them along with messages.

What is HISTORY "HISTORY" is a service that engraves a special jewel commemorating the moment in the member-exclusive jewel box within the official Diners Club app every time various milestones are reached, such as the number of years of card contract or when the cumulative amount of card usage reaches a certain amount.

For example, on the 1st anniversary of enrollment, a "Green Zircon" will be presented, and when the cumulative usage amount reaches 1 million yen, an "Aquamarine" will be given. In addition, colorful jewels appropriate for various member actions will be gifted, such as an "Opal" for spending 200,000 yen at fashion-related affiliated merchants.

Examples of virtual jewels that can be acquired When a jewel is presented, a message is attached, providing an opportunity to look back on the time the member and Diners Club have walked together. The collected jewels are displayed in an original jewel box, where members can enjoy their Diners Club history so far.
