　　3. What problems are solved?

　　The ultimate goal of the cash register is to improve cash register efficiency and operate stores digitally. Let’s analyze from the perspective of merchants and customers. What changes have the cash register brought to both parties? What specific problems has it solved?

　　From the perspective of merchants: mainly from the dimensions of financial management and inventory management. As an offline terminal, the cash register can be used as a data information collector for the daily operation of merchants. When customers purchase goods or services offline, the cashier will generate a pending order after selecting the product and placing an order on the cash register, waiting for the customer to pay successfully. The cash register system will update the payment order status, generate a flow, and automatically deduct the inventory of the goods. The original data submitted by the cash register obtained by the merchant backend will display data reports according to different dimensions. Merchants can use mobile apps and backend systems to keep track of the actual store operating data and changes in store inventory in real time.

　　From the customer’s perspective: mainly analyze from the perspective of payment fluency and the experience of the cashier process. When customers check out: customers use many payment methods, but merchants do not support them; the checkout queue is endless; it is impossible to understand the product information and promotional prices… These problems may make customers leave. POS cash registers can solve the above problems: POS cash registers can support multiple payment methods, and the system automatically obtains promotional information prices after the product is entered into the system, thereby improving cashier efficiency.

Sydney, March 11 (Reporters Liang Youchang and Wang Qi) Chinese Ambassador to Australia Xiao Qian said on the 11th that the current world’s major changes unseen in a century are accelerating and many challenges are emerging one after another. China-Australia cooperation is not only in line with the common interests of the two countries, but also conducive to peace, stability and prosperity in the region and even the world.

Xiao Qian delivered a speech when attending the 2024 Australia Financial Review Business Summit in Sydney that day, saying that China and Australia are both important countries in the Asia-Pacific region. The economic structures of the two countries are highly complementary and pragmatic cooperation is mutually beneficial and win-win. To achieve this goal, it is crucial to establish a correct understanding of each other, deepen practical cooperation, and properly handle differences.

Xiao Qian said that this year marks the 10th anniversary of the establishment of a comprehensive strategic partnership between China and Australia. The so-called comprehensive means that China-Australia relations are not just cooperation in the economic and trade fields, but cooperation in any potential field and level. The so-called strategy means that the importance of bilateral relations transcends bilateral relations and has regional and even global significance. The so-called partner means that China and Australia should become mutually trusting friends rather than enemies, partners rather than opponents.

Xiao Qian said that practical cooperation between China and Australia is very important to both countries. The two sides should continue to consolidate and deepen cooperation in traditional fields such as energy, mining, agriculture, education, and tourism, and expand cooperation in emerging fields such as climate change, electric vehicles, artificial intelligence, health industry, green economy, digital economy, and technological innovation. These will help China and Australia open a new chapter of broader and mutually beneficial cooperation on the basis of continuously consolidating cooperation in existing fields.

Xiao Qian pointed out that both sides should focus on the overall situation, focus on consensus, respect each other’s core interests and major concerns, and manage differences in a proper, mature and intelligent way through friendly communication and consultation.

The 2024 Australia Financial Review Business Summit will be held in Sydney from March 11 to 12. Government officials such as Australia Foreign Minister Wong Ying-hsien, Treasury Secretary Chalmers, as well as opposition leader Dutton, local business executives, experts and scholars attended the meeting to analyze and study the international situation, focus on Australia’s future development, and explore cooperative measures to respond to challenges.
