"Using a Visa Electron" is like "using a Laser card" - there is only one thing called "Visa Electron" just like there is only one thing known as "Laser card". But there are many banks issuing those and each sets their own terms and conditions. It is very well possible there is some place that does Visa Electron with a one-off €10 charge. If you are booking more expensive flights, this might be a better deal than Entropay's offer. If you ever find out what bank does these €10 Electron cards, you might want to post it here for the benefit of other AAM users.
