How not to forget the PIN to the plastic card
In the year N, he worked in town N on a startup N. Advertised through Google AdWords and used a bank card issued for me to pay. When I left for Moscow, I left the card to a colleague to use it in order to pay for the context ...
Last week, a friend called and said that the project was soon “minimized,” and he wanted to get the balance from the card. He called to ask me the PIN of the card, which he lost and which I don’t remember ...
There was a question, how to get money without my presence in the city of N?
No We'll have to go to a bank branch in Moscow, receive money and send it to a friend with a transfer.
I thought about it, but do I remember all my cards (I have 4 of them, if I add another “Raspberry” card, then five) PIN codes? It turned out that I only remember two: salary and a card to pay off a loan. To the other two, which I use to pay for goods on the Internet, I don’t remember, for “Raspberry” I found it in an envelope. In general, “remembering” the codes proved problematic.
What if I urgently need to withdraw money from my card at an ATM? What to do?
Get all the codes in the phone somewhere under the password? I will lose the phone, I can change it (I change it once a year or two, more often than the “card lifetime”) and I will forget to copy the codes to a new phone.
Store online? It is not always possible to get into the Internet from the phone, and it takes time.

I want to talk about the way that helped me solve this problem and maybe someone else can be useful.
We come up with some 4-digit number that we will always remember - for example, your year of birth, or the year of Pushkin’s birth. Next, take the PIN of the card and add the numbers with this number, and if the value turned out to be more than 10, then subtract 10. Write the resulting number on the back of the card, where there is a signature band. As you need a PIN, restore in the reverse order, simple arithmetic.
Example:
PIN: 9276
Code number: 2010
"Encrypt":
[9] [2] [7] [6]
[2] [0] [1] [0]
[11] [2] [8] [6]
[1] [2] [8] [6]
We get: 1286
I already signed my two cards
I note that this method can only be useful for storing the PIN-code with the card, so as not to forget / lose it.
