So of the US companies that do offer hardware security tokens (First Tech Federal Credit, HSBC, USAA, Wells Fargo) none of them offer savings yields greater than 1%. The split is dramatic I have to wonder if there is some deeper reason that companies with higher yields do not want to offer better security. For example, Barclays UK will provide a hardware token, but Barclays in the US will not.
