There were one of the first to have internet banking, back in the early 90's on Compuserve as TSB, and now it appears they're stepping up online security 
The new device, keyring-sized, creates a random number which will be used in conjunction with the current security measures in place. Apparently this is to combat the newer sniffer systems that can capture the screen display as an image, therefore getting hold of the random information you type in in order to get the complete word, sequence of numbers, etc...
Looking forward to see how this pans out, although having another piece of plastic on the keyring will be a bind
