What are OTP and 3DS?
OTP (One-time password): A one-time payment confirmation code sent through your personal Telegram bot.
3D Secure (Static password): A static card password set during card creation, used for transaction verification. You can also find it in your card details.
All of our virtual cards support 3DS, and you can obtain your 3DS/OTP codes through your personal Telegram bot. Follow these steps to set it up:
Go to your Combo Cards account and navigate to Settings → Notifications → Telegram account chat token - For yourself or group chat. Then, copy the address from the pop-up window.
Click the Bot button, press Start, and paste the address you copied from your account.
You're all set up!
