The nation's first blockchain-based e-invoice for tourist attractions was issued via the smartphone app "You Yunnan" at the 2019 "Digital Yunnan" Blockchain International Forum held in Kunming, southwest China's Yunnan Province, on Saturday.

The blockchain e-invoice differs from the traditional invoice in that the issuance is much quicker, easier and safer. All you have to do is submit the applications for the invoice through the app, and the e-invoice will be sent to your email box within 48 hours. 

It will save significant costs of printing traditional paper invoices for the tourist attractions in the province and also makes it impossible to tamper with invoice information, according to the organizing committee of the forum.

It also marks a big step in the application of blockchain in terms of tax and tourism as well as a milestone in the construction of "Digital Yunnan."

More destinations in Yunnan will further promote the idea of smart tourism, allowing tourists to purchase tickets online, and be admitted via e-tickets or facial recognition.

Over 1,000 guests from governments, research institutions and internet companies of more than 10 countries and regions, including the U.K. and France, attended the forum.
