Hi there! Sorry to hear you're having trouble with your American-issued credit card not being accepted on the G7 Taxi app. To help you better, could you please tell me:

- Are you trying to add the card for payment or are you getting an error during booking?
- Have you tried using the card on both the app and the website?
- Is your card enabled for international or online transactions?
- Are you receiving any specific error messages?

Based on what other users have experienced, G7 Taxi's payment system sometimes has difficulty processing foreign (including American) credit cards, possibly due to security measures like 3D Secure (3DS) authentication or restrictions from your card issuer. Sometimes the transaction may not prompt the usual authorization codes needed.

Here’s a step-by-step plan to try resolving this:

1. Verify Card Settings:
Check with your bank or credit card provider that your card is authorized for international transactions and online purchases. Sometimes they block transactions in foreign currencies or from foreign merchants for security.

2. Try 3D Secure Authentication:
If your card supports 3DS, make sure you have set up the verification method (like receiving SMS codes) as this helps prevent rejection. If the app tries to authorize without notifying you, the transaction might silently fail.

3. Use a Different Card or Payment Method:
If possible, try a different card (for example, a European-issued card, or a PayPal-linked card if the app supports it) to see if payment goes through.

4. Clear App Cache or Reinstall:
Sometimes residual data may cause issues. On your Windows device using the WebKit browser, clear your browsing cache or try using the G7 app on a mobile device if you have one to see if it makes a difference.

5. Contact G7 Support:
If none of these steps help, it’s best to contact G7’s customer service via email at [email protected] to confirm if your card type is currently supported or if there's a known issue with American cards on their system.

I can also help confirm if there are recent outages or system issues affecting foreign credit card payments.

Let me know what you’ve tried already or if you would like me to guide you through any of these steps in detail! Are you satisfied with this initial approach?

Cannot use G7 ap on my iphone ... getting error during booking. The ap has allowed me to load the card information.

Thanks for the extra info! You're able to add your American credit card details in the G7 Taxi app on your iPhone, but get an error when trying to book a ride, right? That definitely helps narrow things down.

Based on what other users have reported recently, this type of error often relates to 3D Secure authentication issues with US credit cards on the G7 app. The error tends to occur during the payment authorization step, where the app expects a 3D Secure confirmation but either your bank doesn't prompt you, or the G7 app cannot successfully complete the verification. This can cause a “General Booking Error” or a similar message when you hit book1 2.

Here’s what I recommend trying next:

1. Check 3D Secure Settings: Contact your US card issuer and verify that 3D Secure (sometimes called Verified by Visa or Mastercard SecureCode) is activated for your card and that you’re set up to receive authentication prompts (SMS, app notifications).

2. Try Payment Outside the App: If possible, check if your card works for other apps or services that use 3D Secure to confirm it’s not a bank-side block.

3. Use a VPN or Disable It: Occasionally, being outside France causes the app or bank to reject the transaction. If you’re abroad, try disabling any VPN, or conversely, using a French VPN might help.

4. Update or Reinstall the App: Make sure you have the latest G7 app version installed. Sometimes updates fix payment bugs.

5. Try a Different Card: If available, test with a different credit card (preferably from a French or European bank) or another payment method.

6. Contact G7 Support: For persistent issues, you might want to reach out to G7 directly at [email protected] to ask if they currently support US credit cards in the app or if any outage is affecting payments2.

Would you like me to guide you through contacting your bank about the 3D Secure settings, or trying some of these steps? Are you satisfied with this approach so far?
