Payment Security - Frequently Asked Questions

How OnusCash Protects You from Duplicate Charges

At OnusCash, we understand that network issues and connectivity problems can happen. That’s why we’ve implemented advanced payment protection to ensure you’re never charged twice for the same transaction.


What is Payment Protection?

Payment protection (also called “idempotency”) ensures that if you experience a network timeout or connection issue during a payment, you won’t be charged multiple times. Even if you click “Pay” multiple times, our system recognizes it’s the same payment and processes it only once.

How It Works

  1. You initiate a payment - Click “Pay” in the app
  2. Network issue occurs - Your connection times out
  3. You try again - Click “Pay” again
  4. We protect you - Our system recognizes the duplicate and prevents double charging

Result: You’re charged only once, even if you clicked multiple times ✅


Common Questions

What happens if my payment times out?

If your payment times out due to network issues:

  1. Don’t worry - Your payment is protected
  2. Try again - You can safely retry the payment
  3. Check your history - View your transaction history to confirm
  4. No duplicate charges - Our system prevents double charging

Can I be charged twice by accident?

No. Our payment protection system ensures that:

  • ✅ Network retries don’t create duplicate charges
  • ✅ Multiple button clicks are recognized as the same payment
  • ✅ Connection timeouts don’t result in double charges
  • ✅ Every payment is tracked from start to finish

How do I know my payment went through?

After a successful payment, you’ll see:

  1. Confirmation screen - Immediate confirmation in the app
  2. Transaction history - Payment appears in your history
  3. Receipt - Digital receipt available for download
  4. Notification - Push notification confirming payment

What if I see “Transaction already processed”?

This message means:

  • ✅ Your payment was successful
  • ✅ You’re trying to pay again with the same request
  • ✅ No duplicate charge will occur
  • ✅ Check your transaction history to confirm

This is normal - it’s our system protecting you from duplicate charges.

My payment is showing as “pending” - what should I do?

If your payment shows as “pending”:

  1. Wait 5 minutes - Most payments complete within this time
  2. Check again - Refresh your transaction history
  3. Don’t retry yet - Wait at least 10 minutes before retrying
  4. Contact support - If still pending after 10 minutes

Note: Pending payments are being processed - they’re not lost.
