Anthropic's payment processing and regional prompts differ from OpenAI's. First figure out whether it's a web subscription or an in-app purchase, then decide if you need a virtual card.
Confirm the payment entry point
Don't mix web and in-app purchases. A virtual card mainly helps with the web option.
Activate the card in the MP App
Complete verification, make sure your wallet has a balance, then copy the card number.
Keep the transaction notification
Whether it succeeds or fails, a record is kept in the app, making it easy to compare with the merchant page.
Read the regional and tax notes on the page first.
Don't experiment with three cards on the same subscription at once.

AIThe checkout page asks for a card number. A JKOPay barcode, a convenience-store payment slip, or a LINE Pay transfer can't go in that field.
Getting a cardWhen you search for "Taiwan virtual credit card", you often land on a standalone site that asks for your email. MP Card keeps your account and card in the App, with one less login.
