Don't use the internet for anything business related until business gets serious about fixing the problem. These people just want their profits and, like they learned getting that MBA, the easiest way to do profits is to re-direct costs. In this case, put the costs of doing business online onto the customers. Seriously, who pays the real price when a business gets hacked and all the customer data goes walking out the door/server? The customers suffer from having their data abused, that is who suffers.
Do you trust your ISP with your bank account number, address, phone number, etc? How about your bank? Your employer? Your local utilities? How many of these types of businesses have you seen hacking reports on these past years? All of them, repeatedly, every year.
Do you remember in 1995 when the business and banking communities were warned that the internet was not designed with security in mind, but the complete opposite? Do you remember that they all just said the business opportunities were just too great to ignore and that security would naturally follow usage?
The internet is not for business; the internet is for porn!
