UK here, quite a few banks have used calculator style[0] devices for 2FA. You insert your chip card, enter the PIN and receive a code. The devices themselves, while branded, seem identical across banks and accounts (I can use one I got from bank A for bank B and vice versa). Banks now have introduced app based versions of the above, useful if you've not got the calculator or your card handy, but I don't believe they're looking to phase out the physical device just yet. Seems similar to your device, but instead of an optical sensor to receive a code from the web browser you enter the account code and money amount of a transfer manually.
