Trick to remember multiple Credit/Debit cards PIN?
- Thread starter Manoj Pant
- Start date
Create a pattern.
For example, for a CC:
First digit of card you go from start and use that as your last digit of pin.
Second digit of card traverse from back of card and using 3rd digit of pin.
…
Reverse this for a DC.
If you need to remember many people’s card PIN, add their name’s first or second letter’s position (in a old nokia phone pattern) to your pin.
Make it complex enough nobody else can crack it. But make it simple enough you can remember it 🙂

My almost all txns are online & so I don't need to remember password.
And whenever I need to do offline txn, I simply change it from the app.😅

Easy way: Keep the same PIN
Safer way: Use a function based on the card number e.g
Say the middle set of digits are 6893-2431
Now add the 2 groups together, take only the units part and discard the carry
So 6+2, 8+4, 9+3, 3+1 gives you 8224
Then choose your own personal number. Let us say it is 7
Add this to each digit of the number 8224 and discard the carry. This is your PIN. So it will be 5991
Use digits of 1 5 9 and 13 from card number so that all cards have different pin
challenge with scb cards 6 digit pin so I add 9 in first and last

One way is what SBI debit card teaches you?
2 digits from them + 2 digits from you.
2 digits from them = use your credit card to get 2 digits, use same pattern for all cards
(ex: as suggested by @Wealth is my birth right! , ex: 1 & 5 digits etc.)
2 digits from you = do something to earlier 2 digits (divide,multiply etc.) get another 2.
(ex: as suggested by @Copycat , add your personal number to each of those 2 digits).
its actually easy once you find pattern, don't stress much.

pin = first 4 digits of (sin x+1)log(sin x+1)+x cosx sinx+1 where x is my card number

If card number is 8874-0988-2344-5768 then keep all first digits as PIN = 8025
I use a Password Mamager to remember all those things. If my master credentials are leaked. I will be in deeeep sh!t

Which bank ask you to mandatorily change card PIN?
I know about netbanking passwords but didn't much about debit/credit card PINs. It's usually in our hand until something happened or we want to change and in that case we have to remember or change approach.
He is not talking about Card Pin, he is talking about Bank App PIN.

I have the same pin across all my DCs and CCs. I keep all the usage limits to the bare minimum on the cards I don't carry around in my daily wallet. The ones that I do carry with me have transaction limits set as per my regular usage.
Is there any benefit to having multiple pins?

The real headache starts when you have to change one of those PINs, now either you change PIN for all 25 of your Cards, or you try to remember which logic was used for which card.

I am using a Notes app to keep track of all Cards, Bank account details, all email and app passwords and I keep it hidden from the app list. No one can find it even on an unlocked phone except me.
Also I keep the transaction limits to bare minimum and always turn off International and ATM transactions for all cards, disable Tap n pay for those which I don't use.
Also I have learnt not to save card details in websites and apps except for a few trusted ones. I use Flipkart every month but none of my cards are saved there whereas in Amazon, Paytm etc all cards are saved.

Make an encrypted excel file and store all the passwords there.
Tried this out sometime back keeping the PIN of each card as the birthday of my exes. Unfortunately, I ran out of cards. (Btw, I hold 20+ cards) 🤣
Will delete this after some time because my gf and I share this account 😅
