jourdain On line banking is nothing to do with this 'virtual currency'.
If you follow the rules, on line banking is 100% safe. I do not see how in the modern world it is possible to manage without it. It is safer than ordinary banking.
I am with Barclays , to log in you need your bank card and a 'pin sentry' pad.
The pin sentry looks like a small pocket calculator.
You enter your card number on the on line banking site.
You then put the card in the pin sentry reader and enter your PIN.
The card reader then gives you an 8 digit code to enter on the bank online site.
Only when you have entered the 8 digit code can you access your account.
The code is different every time you log in, even if it is only a few seconds later. You can't get the code without actually having the card with you and putting it in the card reader.
Get a code wrong 3 times and the account locks you out until you go to the bank and get it unlocked.
Never had a hint of a problem in 10 years with 3 accounts.
