Bunca - 我的 AI 用卡回饋神對友

The same purchase can yield vastly different rewards depending on which cards you use.

Whether at convenience stores, online shopping, or paying utility bills, which payment method—LINE Pay, JKO Pay, Apple Pay, or a physical card—is the most cost-effective?

Open Bunca and let its AI help you find the most suitable card before you even pay.

▌ What does Bunca solve for you?

Credit card reward rules are becoming increasingly complex, with payment methods, reward limits, login requirements, and exclusion clauses often differing.

Most people don't lack the desire for rewards; they simply can't afford to research them every time they make a payment.

Bunca will directly tell you how to get the best reward for your purchase based on the cards you already own,

saving you the trouble of checking official websites, comparing rules, and worrying about making mistakes.

▌ When will you use it?

• Want to know which card to use before checkout?

• Want to compare different payment methods before placing an online order?

• Want to confirm rewards before paying bills, insurance premiums, or traveling?

• Want to know if there are spending limits, exclusions, or special restrictions?

▌ Why is it worth trying first?

• No card number required: Just check the cards you already own; no sensitive personal information needed.

• Start for free: Use core features immediately after registration.

• Start with your existing cards: No need to apply for a new card just for referral results.

• More than just answers, we explain the reasons: View payment methods, reward limits, exclusions, and referral logic.

▌ How will you use Bunca?

• Open the Bunca App on your Android phone and check before payment:

"Which card should I use to pay at the convenience store?"

"Which card should I use to pay the bill?"

"Is it more cost-effective to use LINE Pay, JKO Pay, Apple Pay, or a physical card for this purchase?"

• When shopping online on a computer, you can also use the Chrome extension:

On the shopping cart page of supported platforms such as Coupang, momo, and PChome,

you can see at a glance which card offers higher rewards and by how much.

▌ What is currently supported?

• Cash rewards

• Points (LINE Points, JKO Coins, Little Tree Points, etc.) with a 1:1 cash equivalent

• Department store anniversary sales (gifts with purchase + specific card stacking)

• Airline miles are not currently supported.

▌ Additional notes

• The Bunca App can be used directly on mobile devices.

• For desktop shopping experience, the Chrome extension currently only supports Chrome and Chromium-based browsers.
