From the Canadian perspective, people can have credit cards (16 digit chip & PIN for Visa/Mastercard, others only 16 digits) and/or bank/interact debit cards (also 16 digit chip&PIN).  The former are able to be used online; debit cards are for in-person transactions with very, very few exceptions.
 
Visa and Mastercard offer prepaid debit cards; however, their purchase fee is typically 10% of the value of the card (a $500 card costs $50) and the currency exchange rates and service charges associated with using a different currency is usually double or triple what banks or Paypal charge.  The *real* cost of Wikimania registration using one of those debit cards would be approximately 40% higher than the face value of what Wikimania was actually charging. 
 
Unless I miss my guess, scholarships are being paid to people via Paypal.  I think that really points to the necessity of accepting at least Paypal as an acceptable alternative payment.

Roan,

I don't mean to sound daft, but Chip & PIN cards are (at least here) MasterCard/Visa cards with 16-digit numbers. The two are the same?

The reason people are cautious about giving out bank details is because of things like this: http://www.museumofhoaxes.com/hoax/weblog/permalink/clarksons_account_gets_hacked/ ...

But yes, if your debit card has a logo for one of the big payment processors, then most merchants displaying that logo should be able to accept it, even if their transactions use a credit function rather than the debit function.

The problem is that in many continental European countries, MasterCard/Visa cards with 16-digit numbers etc are things that most people don't have. Payments are made using chip&PIN cards or bank transfer.

I've always been baffled by how hesitant UK-based individuals and companies are to give me their bank account information (so I can send them money), citing security concerns.
