联合国推动航空旅行数字化：登机牌和值机或成历史
联合国国际民航组织（ICAO）正推动航空旅行全面数字化，计划三年内推出"数字旅行凭证"系统。乘客通过手机存储护照信息的"旅程通行证"，配合机场面部识别技术，将彻底取代传统登机牌和值机流程。
旅行科技公司Amadeus表示，这将是航空业50年来最大变革。系统将实现动态更新：若乘客因延误错过转机，手机会自动接收新航班信息并更新通行证。机场需升级面部识别等基础设施以支持新系统，Amadeus强调乘客数据会在接触终端15秒后自动清除以保障隐私。

You guessed it – the internet is your friend. A good place to start looking for Telegram channels is Reddit. This is one of the biggest sites on the internet, with millions of communities, including those from Telegram.Then, you can search one of the many dedicated websites for Telegram channel searching. One of them is telegram-group.com. This website has many categories and a really simple user interface. Another great site is telegram channels.me. It has even more channels than the previous one, and an even better user experience.These are just some of the many available websites. You can look them up online if you’re not satisfied with these two. All of these sites list only public channels. If you want to join a private channel, you’ll have to ask one of its members to invite you.
Like a stock, you can buy and hold Bitcoin as an investment. You can even now do so in special retirement accounts called Bitcoin IRAs. No matter where you choose to hold your Bitcoin, people’s philosophies on how to invest it vary: Some buy and hold long term, some buy and aim to sell after a price rally, and others bet on its price decreasing. Bitcoin’s price over time has experienced big price swings, going as low as $5,165 and as high as $28,990 in 2020 alone. “I think in some places, people might be using Bitcoin to pay for things, but the truth is that it’s an asset that looks like it’s going to be increasing in value relatively quickly for some time,” Marquez says. “So why would you sell something that’s going to be worth so much more next year than it is today? The majority of people that hold it are long-term investors.”
