Why do I have a $50 authorization on my account when I haven't purchased $50 in fuel?
When you use your Visa Electron card to make a fuel purchase at the pump, we will authorize your transaction for US $50, as we do not know how much fuel you intend to purchase. These authorizations are removed from your account when the actual fuel purchase amount is received from the gas station merchant, usually within 7 to 10 business days.
