Why am I getting "חסרה כניסה בוקטור 90" (error code 120) from SHVA when trying to Authorize or Charge a payment?

The error "חסרה כניסה בוקטור 90" (provider response code 120) is received from SHVA and the credit card companies when the credit card number entered during checkout is wrong.

In this case, you are required to contact your customer and ask him to verify and re-enter their card number on the checkout page.
