Ideal is not the same, by any means, as PayPal. Read up.
With ideal you loose your money. Ideal is made from the pov of the bank and the shop selling you stuff. Its almost impossible to claim your money back without the sellers consent.
Tikkie is not the same as PayPal since tikkie only works with EU banks. (and quite possibly at this moment only NL banks) PayPal does not need a bank account. Its also not really a wrapper around ideal but thats another discussion. And mostly a semantic one so lets not go there.
Effe wat meer moeite doen en de kleine lettertjes lezen medenedelander :)
