[Skunkworks] KCB ATM/Debit Card (Visa Electron) is being rejected during online purchases

Hi Guys, Is there anyone on the list who uses his/her KCB ATM/Debit Card (Visa Electron) for online purchases? I have just acquired one after opening a bankika account and I was told that I can use it online, but so far it has been rejected on websites that even accept Visa Electron debit cards... Does KCB have to activate something on their side so that the debit card can be used online? Claire.
