[Tipp2014] Fee payment

Hello, I'm dr. Carlos Maximiliano Mollo, I regitered online but my institute (INFN Napoli) has problems with bank transfers at the moment. Can I pay the fee in cash or by credit card at the conference? I will come to Amsterdam on Monday afternoon and then I can be there on Tuesday morning. Even a colleague of mine has the same problem (dr. Daniel Vivolo), but he will come Wednesday. thanks
