The au PAY Prepaid Card is a prepaid Mastercard linked to the au PAY balance, offered within the KDDI/au ecosystem in Japan.
It lets you load money in advance and use it for everyday shopping in stores, online, and at many overseas merchants.
Because it is prepaid, you use only the funds you have charged and do not carry a credit balance.
What the au PAY Prepaid Card Is
The au PAY Prepaid Card is a Mastercard-branded prepaid card issued by au Payment Corporation and connected to your au PAY account.
You load money into your au PAY balance and then spend from that balance through the card.
It can be used at Mastercard in Japan and many merchants abroad, as well as certain online merchants that accept WebMoney-related payments.
The card is not a credit card, so there is no revolving borrowing, no traditional credit limit, and no monthly bill.
Two main formats
A virtual card and a plastic card. The virtual card exists only inside the au PAY app and is aimed at online shopping and mobile wallets.
The plastic card adds an IC chip and contactless functionality and is used in physical stores.
Main Features and Rewards
When you pay with the au PAY Prepaid Card, you earn Ponta points on your spending.
The standard reward rate is 1 Ponta point for every ¥200 (tax included) spent, which is equivalent to a 0.5% return.
In some campaigns or at selected partner shops, the effective return can be higher, but the base rate remains 0.5%.
PAY ecosystem integration
You can charge your au PAY balance from au Jibun Bank, Seven Bank ATMs, and other available methods, depending on your setup.
You can also register the virtual card in Apple Pay and use it for contactless payments at compatible merchants.
For many users who already use au services, this integration makes it easier to consolidate spending and point accumulation in a single system.
Fees and Charges
Because the au PAY Prepaid Card is a prepaid product, there is no revolving balance and no purchase interest in the usual credit-card sense.
You spend only the amount you have loaded, so the interest rate on card spending is effectively 0% per year.
At the same time, the money stored in your au PAY balance is not treated as a bank deposit and does not earn interest.
Plastic au PAY Prepaid Card
- Issue fee: ¥600 (tax included).
- Annual fee: ¥0.
Virtual au PAY Prepaid Card
- Issue fee: ¥0.
- Annual fee: ¥0.
Charging the card from certain methods is generally free from the au PAY side, although individual banks or ATMs may charge their own fees.
There are minimum charge amounts and daily or monthly limits that depend on the method you select.
These limits are defined in the official terms of use and can change over time.
Eligibility and Who Can Apply
To apply for the au PAY Prepaid Card, you generally need an au ID that meets certain requirements.
An individual contract for au mobile, au Hikari, au Hikari Chura, or an eligible UQ mobile (5G) plan linked to your au ID.
Or an au Jibun Bank account linked to au PAY, or identity verification completed in the au PAY app.
Details
Corporate contracts, some MVNO lines, and prepaid mobile contracts may not qualify.
If an au ID is registered under someone else’s line, the card is typically issued in the name of the line owner.
There is no credit screening in the same way as a credit card, but identity verification and eligibility checks based on au’s internal rules still apply.

You can apply online through the au PAY website or a physical au Style/au shop.
The steps are usually simple and can be completed in a few minutes if your au ID is in order.

You load funds into your au PAY balance, earn 0.5% in Ponta points on most purchases, and avoid annual fees and purchase interest.
