Before KiasuMiles

Eight cards.
One cashier.
Two seconds.

You know one of your cards is the right one. You just can't remember which. The cashier is waiting. You tap the same one you always tap. Miles game lost on the small stuff.

Step 1

Tell it once.

Save your wallet. Your partner's wallet. Your parents' wallets. KiasuMiles remembers each one. Different person, different best answer at the same merchant.

Step 2

Ask. Every
step is shown.

No black box. The agent identifies the merchant, looks up the MCC code, filters to the cards you actually carry, ranks the options. Every lookup is traceable.

Step 3

One clear

One skill. Different wallets.
Different answers.
