Hmmm, that is probably why I said recognised bank. Like it would be OK for Santander, etc.
Again, there is no system in place for a teller to just "call up" the bank in Spain. It needs to go through the proper challens which takes a while. "Ringing up" would be as close as you get to a "wire transfer" (which got it's name from the copper wire used in the olden days for the message to be sent. A bit of trivia: checksums were also invented/used then, when a transfer occured some "random" numbers were also sent, to verify the authenticity of the message. Only the sender and recipient would know that the numbers would equal all the digits of the transfer accounts added together, or some other code. Hence, if the someone at one of the repeaters modified the transfer, it could be detected)
best way is bank to bank transfer using BIC/IBAN
unlike a cheque, its fully cleared funds the minute it hits your account. Well thats my understanding
Again, bank transfers also have issues. A common scam is to use a stolen bank account. Another is to cash in a large foreign cheque from a "fake" or nonexistent bank. Let's say Bank42 is the fake bank and BankH is the real bank.
I'll print a cheque drawn on Bank42 funds, in China (much less suspicious than Nigeria, but with different enough systems and regulations to throw a spanner in the process). I will cash this into a real account at BankH (set up just for this under a fake identity), which is a real bank. BankH will duly put the money in my account a few working days after, with a note saying that the money can be reversed at any time until they cash the money from Bank42.
I then initiate a wire transfer to the sellers account/bank, the money goes through, I pick up the car, ship it to Nigeria and dissapear into the woodwork.
A few weeks later, the whole thing is discovered to be fraudulent and money is lost all round. Depending on the legal rights in the various contries, the banks may need to stump up the money, but more often than not, it's the seller that's out of pocket.
