[Hidden-tech] Anyone understand international transactions?

[Claire Huttlinger]

I am being paid by a client in Spain, and they are asking me for an IBAN (International Bank Account Number) and a BIC (Bank Identifier Code)
Can I get these from my bank?  Is it safe to send these over the internet?  Do they need to be converted for different countries?  
I don’t want my profound ignorance to show in this transaction.
Thanks!
