ApplePay is a work of Art that enables online and in-store transactions, but how? 👇

In this specific payment scenario, ApplePay uses to send payment data to the contactless POS terminal with its Tap & Pay feature.

🔸At checkout, a consumer chooses ApplePay to purchase a good or service. First, they need to themselves to the IPhone Secure Element (SE) using Biometrics (Fingerprint, Face ID or PIN).

🔸Once authentificated, the Secure Element generates a , combination of Payment Token, Transaction Amount, Transaction Counter etc and a . The Secure Element passes the Payment Token (DAN), Dynamic Cryptogram and Dynamic CVV alongside other information to the POS Terminal via NFC.

🔸 The POS sends this request to the Bank (Merchant Bank, Nuvei, Stripe…) which in turn forwards it to the Payment Network i.e. Visa, Mastercard etc.

🔸The Payment Network (also called Card Network) identifies the specific Payment Token and passes it and the Dynamic Cryptogram to the Token Service Provider ( ) to obtain a Payment Card Number ( ).

🔸The Token Service Provider receives the Payment Token ( ) and the Dynamic Cryptogram. After verification, it returns a real PAN to the Payment Network.

🔸The Payment Network passes the PAN along with the transaction details and CVV to the Bank - Wells Fargo, Bank of America for authorization.

🔸The Issuer validates the request by deciphering the Dynamic CVV using its private key to check the credit balance against the transaction amount.

🔸If authorized, the Issuer Bank passes back the authorization response to the Payment Network, back to the Acquirer and finally the POS system of the Merchant ✅

This happens lightning fast ⚡️and with extreme convenience. Apple built its payment ecosystem with Apple Card, Apple Cash, ApplePay Later and various other services like In-app payments to achieve a seamless User Experience ( ) to both the Merchant and Consumer.

The FTX story keeps getting crazier every day 🤯

Here are 6 shocking new details that just came out👇🏼

(1) Sam Bankman-Fried’s (SBF) parents own a $16.4 million vacation home in the Bahamas🇧🇸. They are both successful professors at Stanford but the average total pay there is around $185,000 per year. It’s hard to imagine they didn’t get some help from their former billionaire son in affording such a home 👀

(2) One home clearly wasn’t enough as SBF’s parents purchased 19 properties worth at least $121 million in the Bahamas over the past two years. Effective Altruism at its finest? 🤔

(3) FTX and Alameda Research lost $3.7 billion before 2022. The fact they lost staggering amounts of money even during the bull market destroys the image SBF was a genius and that his companies were highly profitable. In reality, they were losing lots of money while likely funding everything with new customer deposits 💸

(4) Digital asset brokerage Genesis received over $1 billion from Alameda and FTX in the last 3 months. All in FTT, FTX native token 🤡 The company is now trying to secure new capital and warns of bankruptcy without new funding. This could cause ripple effects on the whole industry 🌪

(5) Sports stars Tom Brady and Steph Curry are being investigated for promoting FTX 🚨

(6) US prosecutors opened a secret probe of FTX months before its collapse. It’s yet unclear why nothing has been done to prevent the crash 💥

This seems to never end and the rabbit hole just keeps getting deeper and deeper on the FTX mess.

The worst part is that the damage in investor confidence that SBF and FTX have created will cost trillions.

Don't give up early, or be too yourself.
When I received my first company's offer with a sky-high salary (at that time), after my initial overwhelm, I was afraid: fear of failure probation. The first week scared me even more because of my new knowledge, English, abbreviated terms, the pressure I felt and the scariest thing was my boss's goodness. Everyone is so good at making themselves threaten themselves that they will consider themselves shrimp.
When I received the pass probation letter, I asked my boss why I got a pass even though I did it. The boss said: I see you put in a lot of effort and you can train.
You can train. That means my stupidity will gradually diminish.
But I'm still afraid of being wrong. Afraid of not the right boss, not the right customer. Every time I go wrong, I almost lose sleep and torment myself.
I felt like nothing in those days.
But instead of giving up, I told my boss. Boss, I think I'm so bad. The boss said: your experience is too little, making mistakes is normal. Importantly:
- Never make 1 mistake 2 times. That's very stupid.
- Don't be afraid to make mistakes. You just do it. You have common sense and you're not an ignorant person so your fault won't be the kind of thing that's wrong, there's me back up. Wrong I corrected.
- Don't take it personally when you make a mistake and I yell. Work is work, when I personally offend, then you tell me to fix it.
- The more you are afraid, the more careful you have to be. Before sending something checked 1 time is not enough, 3 times. Reading and seeing the pressure, I read it here and then I corrected it. Don't be shy.
- If you look at your colleagues, whatever their fault is, I can dodge.
- I hate the kind of error that I don't know why. For all we do, we have to know why we're doing it. It's okay to be wrong, there has to be a reason. For a reason, I will analyze the error and give the right one.
- root cause. For this error, what is the root cause and what is prevention action.
- Do whatever it takes to predict what the outcome will be. Given as many scenarios, the easier it is to dodge the wrong path.
- Raise the standard. If you do anything, you don't see the error all your life.
- And don't give up. I'm sure you're not stupid, it's your fault for being reckless and inexperienced. You have to heal yourself.
So guys. If at some point you feel that you are too bad or have not improved at all, do not give up but bravely confront it. Analyze why and how solutions.
Tell your boss how you're feeling. The boss will give 1 dose or special medicine or tonic, any kind will be better.
Don't run away. Give yourself that opportunity to let me fix, and boss. No crazy boss keeps 1 guy who just vandalized and doesn't see the way out.
Then tomorrow will be better!

The Framework

At a high level, the intent of the Agile Innovation Framework is to connect vision to value, and strategy to ex*****on in a simple, visual way.

The purpose is to help leaders reimagine their Future Business by zooming out and stepping into the areas that represent the most important choice points, strategies, and decisions.

Customer Scenario Patterns are the backbone of the Agile Innovation Framework with a focus on addressing customer pains, needs, and desired outcomes in an agile way.
Here is a look from the balcony view:

When I explain the Agile Innovation Framework at a high level to folks in the hall, I simply say:

Reimagine – Reimagine the Future Business

Roadmap – Work backwards from the desired Future Business and create a business release roadmap to get there

Results – Drive results

I refer to this as the 3Rs of Digital Transformation and innovation.

The Big Ideas of the Agile Innovation Framework

You can think of the Agile Innovation Framework as a way to storyboard the future business.

I attempted to address several challenges that happen when people try to create their Future Business.

1. Business because of technology.
2. Vision-driven and value-led
3. Customer pains, needs, and desired outcomes
4. Multi-Perspective
5. Multi-Horizon view
6. Scenario-driven approach to chunking big change
7. Exploration and Ex*****on

The Key Elements of the Agile Innovation Framework

1. Imagine if
2. Digital Vision
3. Business Drivers
4. Capability Map
5. Journey Map
6. Scenario Chain
7. Scenario Narrative
8. Solution Storyboard
9. Tech Storyboard
10. Change Benefits
11. Value Touch Points

For a brief moment, Apple was bigger than Amazon, Alphabet Inc., and Meta combined, in terms of market cap.

Apple has managed to remain afloat through this rough market, and they seem ready for any storm that comes their way.

Revolut’s Quest To Become A Financial SuperApp

Antifragile, as described in the eponymous book by Nassim Nicholas Taleb, is used to describe things that gain from disorder and chaos.

The FinTech industry is witnessing a massive turn of fortunes and is experiencing unprecedented disorder and chaos, especially in the consumer-focused segments such as neobanking, BNPL, digital investments, etc.

Plummeting valuations, investment cooldowns, heightened regulatory scrutiny, and recent geopolitical tensions have brought an unwelcome winter for the FinTech industry.

When most of the players in this space have resorted to defensive choices, a UK-based e-money institution with a European banking license is showing the traits of being an antifragile.

Revolut has not just remained immune to the recent downdraft but seems to be scaling new heights amidst the uncertainty and chaos.

In its quest to be a financial super app, Revolut has stuck to its aggressive expansion strategy, persistently increasing its global footprint, backed by a diverse range of products, features, and tools for the customers.

Having already covered the stellar growth in their product offerings from 2015-2020 in their previous deep dive, in this edition, WhiteSight is taking a look at the more recent ones, launched from 2021 onwards.

Great piece, as always!

Having re-shaped both and in the past decade, BuyNowPayLater keeps producing headlines: whereas some are proclaiming its death others are praising Apple for entering the game. Where is the truth? Let’s take a look.

What started as a niche segment offering from specialized players more than a decade ago, has become a multibillion industry that nobody can ignore: the global industry is worth about $US157 billion, according to WorldPay’s 2022 Global Payments Report.

The idea of facilitating installment is not new; it actually goes back decades to department stores (especially in the US), however the rise of e-commerce and FinTech , have played a catalyst role in transforming BNPL into what it is today.

Its modern FinTech reincarnation has led to huge success on the basis of a strong dual appeal to both consumers and merchants. For consumers it’s convenience through a streamlined, low-friction, integrated check-out experience, whereas for merchants is boosting conversion rates and average order value.

The pandemic has clearly marked a milestone for the industry with on-line (and mobile) shopping becoming the new norm and BNPL getting a significant chunk. However, the picture has changed dramatically as of late:

– Valuations around the globe have collapsed: US player Affirm now trades at a $5.33 market cap vs a $30 bn peak – a 75% change over a year – whereas in Australia, home to 15 pay-later stocks, the most of any bourse, more than $28 bn of market value has evaporated from the sector, according to Nikkei Asia

– None of the major pure-play BNPL players – the likes of Klarna, Affirm, Afterpay and Zip – is currently profitable

– Klarna, the biggest player of the lot with 147 mn active consumers across more than 400,000 merchants in 45 countries faces a 30% drop of its valuation (from $45.6 to $31 bn) and has announced laying off 10% of its workforce

The reasons are not hard to fathom: rising global interest rates amidst record inflation, a worsening macro environment and the war in Ukraine, mounting losses combined with rising investment focus on profits versus growth and increased regulatory scrutiny.

However, what seems at first glance as a dire situation, is very likely to be the inevitable adjustment following a peak, accelerated by unexpected macro changes:

— BNPL as a whole still holds a tiny market share of global e-commerce (2.9% in 2021) and has ample potential to grow (to 5.3% in 2025 and beyond)

— Apple’s recent move has only reinforced the appeal of the model and its prospects, if done right

— BNPL is clearly transitioning from a somewhat stand-alone proposition to a mass-customization tool that can find its way to wider ecosystems’ offerings as a credible alternative in an increasingly multi-polar payments

To rephrase Mark Twain, the reports of BNPL’s death seem to be greatly exaggerated.

Evolution of the Netflix API architecture.

API-first is a product-centric approach to developing APIs… join us now: https://lnkd.in/dCyFqrz5
The Netflix API architecture went through 4 main stages.

𝐌𝐨𝐧𝐨𝐥𝐢𝐭𝐡. The application is packaged and deployed as a monolith, such as a single Java WAR file, Rails app, etc. Most startups begin with a monolith architecture.

𝐃𝐢𝐫𝐞𝐜𝐭 𝐚𝐜𝐜𝐞𝐬𝐬. In this architecture, a client app can make requests directly to the microservices. With hundreds or even thousands of microservices, exposing all of them to clients is not ideal.

𝐆𝐚𝐭𝐞𝐰𝐚𝐲 𝐚𝐠𝐠𝐫𝐞𝐠𝐚𝐭𝐢𝐨𝐧 𝐥𝐚𝐲𝐞𝐫. Some use cases may span multiple services, we need a gateway aggregation layer. Imagine the Netflix app needs 3 APIs (movie, production, talent) to render the frontend. The gateway aggregation layer makes it possible.

𝐅𝐞𝐝𝐞𝐫𝐚𝐭𝐞𝐝 𝐠𝐚𝐭𝐞𝐰𝐚𝐲. As the number of developers grew and domain complexity increased, developing the API aggregation layer became increasingly harder. GraphQL federation allows Netflix to set up a single GraphQL gateway that fetches data from all the other APIs.

Over to you - why do you think Netflix uses GraphQL instead of RESTful?
