1
Almost everyone knows the Visa brand.
2
One of the most trusted and recognizable in the world.
3
But not everyone knows what Visa does.
4
A credit card company.
5
Not a credit card company.
6
Is it a bank company?
7
Nope.
8
They loan money.
9
Try again.
10
They lend the money to you and then they charge your bank account later.
11
Sorry.
12
I have no idea.
13
Oh!
14
Can I have a clue?
15
Visa is a payments technology company that facilitates commerce around the world.
16
Whether you are making a purchase, sending money to a friend, or part of a business moving money to another business.
17
Visa pioneered the electronic payments business more than 60 years ago, envisioning a world in which paying for something could be translated into electrons
18
and photons that move across the globe at the speed of light.
19
The consumer may access an infinite range of goods and services whenever he chooses, he chooses, wherever he may be.
20
Today, there are more than 3 billion Visa accounts around the world, in more than 200 countries and territories.
21
During fiscal year 2019, more than 200 billion payments in cash transactions were made with the Visa brand,
22
representing more than 11 trillion in payments and cash volume, from the largest cities to remote communities across the globe.
23
Each transaction made on the Visa network represents a packet of data that moves across a massive telecommunications network, more than 10 million miles in length end to end.
24
The network is made up of fiber, ethernet, wireless, satellite, and virtual connections,
25
linking consumers, businesses, governments, and financial institutions.
26
The journey of each transaction starts with you.
27
When you click, swipe, dip, or tap to pay, data about the transaction travels from the store owner to their bank or processor,
28
which captures the information and sends it to Visanet.
29
Visanet uses artificial intelligence technology to analyze every aspect of the transaction to determine the level of risk for fraud.
30
VisaNet routes the information to the bank that issued the customer's credit or debit account.
31
The bank decides whether to approve or decline the transaction based on Visa's risk score and its own data about the account.
32
Traveling back through VisaNet, the approved request returns to the store owner, where where the transaction is completed.
33
Later on, Visa makes sure the money is transferred.
34
This authorization all happens in less than one second, whether you're in Miami, Madrid, or Mumbai.
35
Making sure that every transaction flows instantly are several global data centers synchronized in real time
36
so that if one system experiences issues, another picks up.
37
Software developers and other partners can use Visa's developer tools to build innovative ways to pay.
38
As a payments leader, Visa is extending the boundaries of our network and the potential of billions of connected devices,
39
bringing the security and reliability of our brand to customers across the entire payments ecosystem.
40
Digital commerce can extend to even the most remote regions, where people who don't typically bank can access the benefits of mobile technology.
41
Despite the growth of digital payments, about 1.7 billion people still lack access to formal financial services,
42
and consumers spend nearly $17 trillion in cash and checks.
43
Meeting this opportunity is the mission of Visa's more than 19,000
44
employees committed to accelerating the global migration to digital payments to enable individuals, businesses, and economies to thrive.
45
You might not know what Visa does because the inner workings of our network are not visible when you're making a payment, and they shouldn't be.
46
Speed, security, and convenience are what drive our business, so you can get on with yours, no matter how, when, and where you choose to pay.

シャドーイングとは？英語上達に効果的な理由
シャドーイング（Shadowing）は、もともとプロの通訳者養成プログラムで開発された言語学習法で、多言語習得者として知られるDr. Alexander Arguelles によって広く普及されました。方法はシンプルですが非常に効果的：ネイティブスピーカーの英語を聞きながら、1〜2秒の遅延で声に出してすぐに繰り返す——まるで「影（shadow）」のように話者を追いかけます。文法ドリルや受動的なリスニングと異なり、シャドーイングは脳と口の筋肉が同時にリアルタイムで英語を処理・再現することを強制します。研究により、発音精度、抑揚、リズム、連音、リスニング力、そして会話の流暢さが大幅に向上することが確認されています。IELTSスピーキング対策や自然な英語コミュニケーションを目指す方に特におすすめです。
