There are still a lot of places that are working on it, UK is doing it too. Plus, it is something that will end up working very well for most people, it is going to end up being quite good, there shouldn't really be anything that will take a long time, it's something that will take time and we can do this.
Also we need to realize that governments could make so much money from this and that has to be the key point here, because they know that it's great situation and that has to be the reason they are so interested in making more money and taking more money, that has to be the most important situation. WE need to realize that governments are all interested in making it as big as it gets and that's the trouble so it has to be the key.
UK is advance country where everyone are running to because of the development, there are some countries where half of the population don't have access to internet and it's not like the government isn't ready to implement them, some are just backward despite how things has advanced. Remember that the internet service providers only take masks and cables to the places where internet demand are, they don't waste resources where they will not make money.
The digital payment system is what the government can benefit very well because right now in my country, the government is making billions of revenue in average as they charge VAT for any incoming transactions, this is what they make daily from people that are not even upto half of the population. I can only imagine how big they will make from this if the entire country go digital, that's a huge revenue generation.
