Have you ever wondered why when ever you walk into a bank to use the ATM and swipe your card to withdraw money where you need to type a 4-digit PIN code to authenticate yourself and proceed to withdraw money. However, have you ever thought what is the reason behind 4 digit code?

Why ATM PINs always have a 4 digit code?

ATM as we all know stands for Automated Teller Machine. It was first introduced in the year 1967 and it had been widespread in no-time.

ATM was invented by a well-known Britisher John Adrian Shepherd-Barron. He was born in Shillong and was born to Dorothy Barron (Wimbledon Ladies Double Champion). While testing his invention John Adrian Shepherd-Barron proposed for a 6-digit PIN.
The first person to use his latest invention was his wife, Caroline. Caroline apparently rejected the idea of using a six-digit PIN for her husband’s invention and the reason behind it was surprising.

Caroline rejected the idea of putting the 6-digit code for her husband’s invention just because she could only remember the largest string of 4-digits. So, 6-digit was too long for her to recall.

So, this was the reason why ATM PIN has only 4 digits. Nowadays there are many banks that are offering a 6-digit PIN code for accessing the Debit cards. However, sometimes we even forget our 4-digit code. Just imagine what can happen if the PIN was of 8 digits like we use it on our social media accounts. So, let’s thank that woman for making the code that short because 80% of us would forget it it it was the 6 digit as usual.

The young woman was seen at Joker Nightclub in Benin, where Davido and his crew partied recently. Check out how Instagram users reacted to her picture:

Adobe recently announced Project VoCo — an experimental tool that will allow users to remove and replace certain words in a speech. It even includes adding words that did not initially appear in the audio file.


CREEPY, right?!
.. But I like the whole idea!!

According to TechCrunch, “Project VoCo needs about 20 minutes of voice samples from a given speaker. It then analyzes the speech, breaks it down into phonemes, transcribes it and creates the voice model.”

While this tool might raise ethical alarm bells about the ability to change facts, it could be very useful for vloggers and podcasters.

Unfortunately, this is a prototype and no information on if or when Project VoCo will become a commercially available product.
