The power of a Barcode !!!

As world moving towards digital economies, two issues often come up are security and usability of various transaction methods in this digital world. While security aspect may have multiple layers, usability largely revolves around how easy it is for a customer to pay through digital payment methods.

Many times, when using a digital payment method, consumer or merchant has to enter the instrument no. (Credit card #, or some other Id number) manually, which takes its own time and also makes the method vulnerable to user-side security attacks.

However, this problem can easily be solved by the barcode technology. At zero cost, it can bring in the much-required anonymity in the transactions.

So you may ask what the hell I am talking about and if it's something new, how can it be implemented. Valid questions and this is how we may do it:

Until Credit, debit, and other payment cards start having the only barcode on them and not character string, users can easily create a barcode of any string of characters, which, when scanned with a barcode scanner will regenerate the string. This string can be encoded to ensure it can not be intercepted by external attacks at any point in the network.

Barcode reader & generator are simple apps and don't need any additional hardware. Individual users can carry simple prints of those barcodes and scan them at merchant kiosks or during online payments.

It will not only allow secure Card transaction but also, mobile# based payments, email based payments, and all other kinds of identity-based payments.

Identity payments, in particular, will get the greatest push from this as they are based on individual identities such as SSN (in the USA), SIN (in Canada), Aadhar (in India), and similar in other countries. In many countries, your national identity is a private key (for ex. SSN) that shouldn't be shared with others and therefore payment based on this haven't been expired yet.

Once it could be done through barcode entry method, the biggest concern that didn't allow this possibility from becoming reality will go away.

Cloud Comparison - Part-3: Business Strategy - Get Set Go

All businesses formulate their strategies around their strengths and use partnerships and collaborations to bridge the gaps. The three cloud hyperscalars we are talking about – AWS, Azure, and GCP – also follow a similar approach. Before we go into details about these three players, let me list the main segments of the cloud market. The cloud market is divided into 3 sets of solutions: 1. IaaS (Storage, Compute, Network) Public IaaS – This is the segment with ~$100B market and AWS commands around 55% of the market, followed by Microsoft (30%), Google (10%) Private IaaS (On-premise) – This is a sub-segment within IaaS driven by clients' demand for hybrid cloud solutions. Overall market size is ~$25B led by Microsoft Azure Stack (33%), Google Cloud Anthos (25%), AWS Outposts (15%) Overall IaaS market is led by AWS with more than half of the market share. * Please note, that all numbers mentioned here are approximates and based on the reports ...

Driving - not much different than running an organization!!!

When I hear of the driver-less vehicles OR uberization of transport, I always wonder will it really reduce the number of people who would own the car in future? Do people use these 4-wheels only for commutation? If the answer to the latter is ‘yes’ then the answer to the former one would more likely be ‘Yes’ as well. Regardless of that, for me driving is fun. It is an activity that makes me feel in control of at least something in life. But on top of that, every time I am driving, I and up connecting what happens on the road with the corporate leadership. Here are few of those things that I have deliberated numerous times behind the wheel. Know what you are driving - One shall always understand what you are driving – a bus (large organization), a van (mid-size organization), or a small car. All three will adopt a different culture. While on the bus, co-passengers will have a chance to interact with a large number of people, you, as a driver, may not be able to maneuver it abruptly. Al...

10 Habits That Are Making You Miserable At Work !!!

This story, authored by Jeff Haden , was originally published by Inc. ------------------------------------------------------------------------ Happiness—in your business life and your personal life—is often a matter of subtraction, not addition. Consider, for example, what happens when you stop doing the following 10 things: 1. Blaming. People make mistakes. Employees don't meet your expectations. Vendors don't deliver on time. So you blame them for your problems. But you're also to blame. Maybe you didn't provide enough training. Maybe you didn't build in enough of a buffer. Maybe you asked too much, too soon. Taking responsibility when things go wrong instead of blaming others isn't masochistic, it's empowering—because then you focus on doing things better or smarter next time. And when you get better or smarter, you also get happier. 2. Impressing. No one likes you for your clothes, your car, your possessions, your title, or your accomplishments. Those a...
