I think NIC Bank is the best. There are no restrictions on which browser you are required to use unlike I&M’s and Barclay’s cards that insist on using Internet Explorer.
The 500bob is a one time payment for purchasing the card or obtaining a new one upon expiry (485bob) or loss of the card (500bob).
NIC Bank sms alerts are free, for I&M’s each sms alert costs 5bob.
I think I’m going to get one and use it for trading in USD.
