In Germany, you can still get such devices (for people who don't own smartphones, presumably), but it seems a bit like banks are discouraging them and in any case, they make you pay for them (a one-time cost only, though). So most people will use the smartphone app. The old boxes won't work anymore though. The reason is that with the EU directive PSD2, it became mandated that the codes be tied to the transaction in some way. So the newer devices need some way of reading the transaction info before generating the code, e.g. a QR reader.
