This is followed by the standard authorised / not-authorised response to the acquiring financial institution.

Security concern or ‘pop-up’ 

It is a notification selected in the cardholder’s computer settings.

The browser setting is to warn if one moves from https://… to http://….

The “security” pop-up appears when VCS (https://…) tries to redirect the browser to the http://… response page. The only unencrypted information travelling over this ‘unsecure’ connection would be your VCS terminal Id, reference number, bank response and amount –no card related information!

The programmers at Microsoft etc. could have explained it more clearly like i.e.

“Security Notification: You are now LEAVING a secure site. Any information you enter HEREAFTER is not encrypted….”

When one clicks the Submit button on the VCS payment page VCS processed the transaction.

The transaction was already completed (we’ve already received the bank’s response) when we tried to redirect.

If one clicks the Cancel button on the “security” pop-up, one will only end the browser session.

One will not cancel the VCS transaction by clicking on the Cancel button,  one will only cancel the diversion to the response page.

For an immediate solution to the problem where the cardholder’s browser warns him/her when they move from the VCS https (secure) page to the non secure page, you can do the following:

  1. Buy a security certificate from or from to make your response pages also secure. The cardholder’s browser won’t generate the pop-up warning because the cardholder will stay in a secure environment.
  1. Or one can modify the http method of the response pages to FETCH & POST. VCS (https) will request the approved or declined page from the merchant’s website, store and send the result returned to the cardholder’s browser. In this case the merchant cannot use any relative addressing in the page. The merchant must use absolute addressing in the response pages.

Or one can add the call-back function as a safety net in case a cardholder closes his browser prematurely. The call-back function is a background task to ensure that the merchant is notified a second time in the case where a problem occurred on the cardholder’s browser and the merchant did not receive the original response.

The cardholder loaded a browser setting to warn if they move from https://.. to http://.


The “security” pop-up appeared when VCS (https) tried to redirect her browser to your approved page (http).
