If you join before the age of 39, the annual fee is free. You can earn twice as many points as with a regular JCB card, and the return rate increases when you use designated stores such as Amazon, 7-Eleven, and Starbucks. JCB’s numberless card is also available, and you can choose how to display your card number. In addition, you will receive notifications of your usage via the app, so you can prevent overspending.
