5.

Beijing byte beat Co., Ltd., its proct "Tik tok" recently swept the west, the growth is very rapid. To what extent? Facebook, the social giant, has been alerted by its rapid growth and launched Lasso, a similar proct

do you feel confused, which company is this and what application is it? Tiktok, the domestic version of this application is also a universal proct, and it is the overseas version of the jitter. At present, the download volume of Tik tok on the Appstore has surpassed that of Facebook, and it has become one of the top ten download applications in the world. As of July, the global Mau (monthly active users) was 500 million, and there were more than 6 million users in the United States. Not limited to this, Tik tok is also very popular among young people in Japan, France and New Zealand. Many foreign mainstream media have reported this

the French newspaper Le Figaro recently published a report on why Facebook wants to Tik tok, a star app among teenagers. The New York Times also published an article on it, titled Tik tok, a Chinese video app that brings fun back to social networks

is being looked down on by many people in China, and it has not only succeeded tiktok, conquered the world, but also completed a real cultural output. This is what many Internet giants in China want to do for many years. p>

6. For payment procts, the most concerned issues are fund security, arrival time, credit card amount and

rate points
first of all, let's talk about the security of funds
this involves the concepts of "one clearing" and "two clearing" of capital settlement
one clear settlement: pay the license company directly from the third party payment method of UnionPay or central bank (people's Bank) to the user
clearing settlement: first settle to the first clearing user, then the first clearing user settles to the second clearing user. In this way,

, there are variables in the security of funds
how to judge whether it is "clear"? Whether the payment settlement company is a "payment

license" issued by the central bank. This can be inquired from the people's Bank of China
unbounded uses two channels, tengfutong and Yibao of tengbang international
check the payment license on the official website of the people's Bank of China:
z2006844000016 Shenzhen tengfutong Electronic Payment Technology Co., Ltd.
z2000711000019 Yibao payment Co., Ltd.

another judgment. In credit card consumption, the "transaction description" in the bill prompt (ICBC

is the name of the merchant, construction is the transaction description, instrial bank is the transaction summary, each bank is similar, called

in different ways, but they are all the same thing), "Erqing" will jump code every time consumption, and the title will change every time, Then this must be clear, there will be unsafe factors in this settlement. Unbounded pay uses

the payment channels of "Yibao" and "tengfutong", and each consumption will display the online consumption records with head up. The income settlement is carried out by Yibao and tengbang international, not by unbounded company, and then by unbounded company
tengbang international is a listed company listed on Shenzhen Stock Exchange, code 300178
Yibao payment has met the conditions of domestic gem, but has not been listed. Tang bin, CEO of Yibao payment, said: "at present, the most important thing of Yibao payment is to do a good job in proct service and maximize customer value. We will not rush to consider capital operation and listing, but we will not rule out listing at the right time and place."
in the last year, 10 companies have been listed in succession among the companies cooperating with Yibao. Boyahou

mobile, 500 lottery, Sina Weibo, Jingdong Mall Xunlei, cheetah mobile, Aikang Guobin, letuo game

all have close cooperation with Yibao
the company of unbounded payment, Rongfeng technology, has also obtained the red head document of Shanghai<

let's talk about the time of arrival:
because it is a al channel, the operation is more convenient, t + 0 and T + 1 are available. Let's talk about the arrival time of T + 0
tengfutong's channel can achieve second to account. It will arrive in a few seconds< Since Yibao was connected in May, 2015, there are still some problems that can improve the in-depth cooperation. Before the project, it was only open to collect accounts in time, 5 minutes to 1 hour, and half of them arrived in about 10 minutes<

let's talk about the amount of credit card again:
tengfutong: 20000 for a single card, 100000 for a single day, with unlimited amount of credit per day Risk control period: single card single

4000, single card twice a day. There is no limit to the amount of daily payment)
Yibao payment: 50000 yuan for a single card, 200000 yuan for a single card, and no limit to the amount of daily payment<

finally, there is the problem of rate and points:
rate:
tengfutong D + 0 seconds: 0.45% - 0.7%
tengfutong D + 1:0.40% - 0.55%
Yibao D + 0 seconds: 0.45-0.7%
Yibao D + 1:0.40-0.55%
points:
unbounded app payment belongs to "online consumption", most bank cards carry points, depending on the bank

this question is asked by the unbounded pay help center. If you have any questions, you can go to wujiepay.top/help. Other

related questions can be answered by 400 telephone specialists
