To access Business Internet Banking you need four things present at the same time:
- A PC or laptop with the software that runs the smart card reader installed
- A smart card reader. This is a hardware device, attached to your PC that the smart card is inserted into
- A smart card unique to each individual user. The card will become “locked” if an invalid PIN is entered in excess of a pre defined number of times
- A PIN unique to each individual user.
Unfortunately the Software Requirements link, at the bottom of that page, states only that you need Adobe Acrobat Reader, which I suspect is not the only software requirement!
The Barclays Personal On-line banking works with all the browsers, so if the same is true of the Corporate banking, then it is at least possible that I could install Firefox under Wine on Linux, providing only that I can get the smart card reader to work.
The difficulty would be if it needs Active-X support, which whilst theoretically supported under the latest versions of Wine, would make the proposition very much less likely to work.
