About カードマン:クレカ使い分け
By registering your credit cards, you can find out which card earns you the most points at each store.
■ Best Card for Each Store
Search for a store and you'll see which of your registered cards earns the most points, along with the conditions for doing so. You can search from convenience stores, supermarkets, and drugstores to online shops. You can also find out which cards you don't already own that earn more points at that store.
■ Nearby Stores
Display stores near your current location that offer point bonuses for your registered cards. You can also see other nearby stores. Your location information is used only to find nearby stores and is not saved. Store locations are based on OpenStreetMap data.
■ Card-Specific Reward Rates
Check the basic reward rate and the reward rate at point-boosting stores for each card. Annual fees, international brands, and included insurance are also displayed.
■ Compare by Desired Points
Compare reward rates by converting them to the points you want to accumulate, such as JAL miles, ANA miles, or common points.
■ Annual Fee Renewal Notification
By setting your membership start date, you will receive a notification when your annual fee renewal date approaches, and this will also be displayed in My Card and Card Details. You can also choose to receive daily notifications until you choose to continue or cancel. The renewal date is an estimate calculated from your membership start date. Available with Cardman Gold.
■ No Card Number Required
Only the type of card you own is registered. Card numbers and usage details are not handled. The displayed reward rates are compiled based on official information from the card companies.
■ Cardman Gold
The free plan allows you to register up to 4 cards. Cardman Gold allows you to register 5 or more cards, and also offers features such as points accumulation, point calculation, annual fee renewal notifications, and a gold color scheme. Both plans offer a one-month free trial.
・Monthly Plan: ¥480 (tax included)
・Annual Plan: ¥4,800 (tax included)
Payment will be charged to your Google Play account. It will automatically renew unless you cancel before the end of the period. You can cancel anytime from Google Play.
