Not a device but a lot of norms: Digital everything. Even digital drivers licences. It's a norm to carry only a phone and keys in some parts of the world. Even payments have a different norm. The vending cart lady has tap and go payments and has done for over a decade now. When I moved to the USA I had to buy a wallet for the cards they use here. That was 5 years ago and the USA still isn't there yet. Banking. Not a niche device but there's no need for Venmo or PayPal type apps in much of the world. The government mandates all banking system Apis and there's instant free transfers to other accounts. I just had to pay a $10 transaction fee for a bank transfer in the USA and it was a hassle (not done phone to phone but through routing and bsb numbers). Taxation. It's a government integrated system. It still has a ton of special tax edge cases but for the most part you log in see your employers entered wages and tax paid and acknowledge. It's a much much better app than TurboTax and for the exceptions they are just checkboxes for meeting the criteria and fields for amount spent in the category etc. No TurboTax premium required since it's the government's app. Universal public transit apps. You tap on the ferry with your phone and tap out of the train station later in your trip. It's all integrated. In fact riffing on taxation why isn't there more done online. Why do I need to go to the DMV short of an in person driving test?
