Scan To Pay in 2 Minutes

In India QR code is static for Merchants

Exactly what we need in explanation simple, well-explained, very good, and elegant diagrams thank you very much

2 personas and 2 sub-process:

1. Merchant to generate QR code
2. Consumer to scan QR code

What is PsP gateway?

Great content and topic selection.
I will be more helpful if full form of acronyms are shown on screen, example what's PSP?

Please advise how to draw those beautiful chart & animation chart?

Kroger is using some logic reversely. The app in the mobile device generates the QR code and the console will can the code to finish the payment.

great,
please a video about static qrcode payment

This is overly simplified. This is useless for engineers who want to understand QR code in depth.

Thanks for the Video, but the interesting part about step 9+10 is skipped - what is there happening? (how is it verified, passed on securely, ....)

Thank you, your channel is a treasure.

That was a great quick lesson .. awesome

Hello, nice to meet you here, do you have any courses in udemy or something like that ? I am interested to take lessons from you, you explained very clearly

Bring about static qr code.

Proud that you mentioned PayTM

Just subscribed, great content, I love the visuals, what tool are you using??

Please do cover about the static qr code payment plz!

Waiting for next video about static scan!

This is about qrcode system, the actual transaction would require a payment service. Like for example paytm uses the UPI( unified payment interface), which is build on the IMPS

In Malaysia, they supports three types: static, customer scan merchant & merchant scan customer. Merchant scan customer is where the wallet app generates a unique per transaction QR code, and after scanned by the merchant will display the amount being paid. Not sure if it's fraud-proof though.

yes right, you dont program, you try to get paid, cant do both at same time, choose one, lack in the other

Great explanation 👌
Which software did you use for making this video?

Can you explain, what happens when user click pay button? How the wallet app knows payment has been successful?
Also, user may select different mode for payment like in-wallet balance, Internet banking, UPI, Debit Card, Credit Card, PayLater app etc. , how all these cases are handled?

Best tech content in the most simplied way possible and the key engagement metric is the animation to keep the viewers engaged.

useless comon sense info without explainging challnges and error handling!

Awesome one, would like to see how the data mapping bit works for this with NFRs

Thanks so much for this. Great video and very nice animations.

Hi Alex, thanks for the video! At step 9, what happens if the order is already paid i.e. how do we prevent a double payment?

simple, short and well explained

Great Video.

@alex when can we order your book system design v2 in India?

Very nice video about world's revolunatiry payment midel. Please explain with more details how it works internally.

How does the pay option works with bank? Can you cover that too?

Thanks for the excellent explanation

Great video! Though I'm a bit skeptical about the step number 10, where the payment gateway is notified by customer's device on successful payment. How does that work?

Does the request(step 10) has a secret token attached to it (generated by a bank?) which gets verified by a PSP on receiving it?

only expert can explain this in 2 mins...

so simple and neatly explained!

Awesome animations 👏👏

My man, I absolutely love your content.

gold content

Just awesome content - in 2 minutes!

This is just too simple and well explained. Great job Team 👍👏

Does anyone know how to create such videos? Which software or platform is used to create such amazing videos?

It is not clear from the video where the actual client money are stored. Does the client have an account and some money in PSP system? Or the mentioned Digital Wallet App actually "contains" money on the client's mobile phone?
My guess is that PSP stores client's money (directly or by having access to a credit card added by client) and both client and merchant have PSP access software installed.
And the QR code is required only to "skip" the client identification process in merchant's terminal.
I.e. first the order is "anonymous": "someone wants to spend $10 at merchant's place on order number 12345".
And the client's app says "It's me who wants to pay for that order, take my money from my account."
And in the end PSP says to client "Ok, done, your money spent succesfully" and to merchant "someone has payed on this order, you can give the physical goons to the person now"
Is it close to be correct?

Eye opening!

Interesting topic and well explained as usual!!

Like short videos with specific information

Crisp and clear.Thank you

Fantastic!

Great content.

Thanks for the good content! Would have been nice to also get some information on possible failures of the workflow to know how to these scenarios could be handled
