How to check cards for validity in 2024?
Let's start with the question: on what basis are cards blocked?
There may be 2 reasons for this.
1) The card is blocked automatically. This mainly happens on the initiative of the anti-fraud, if suspicious transactions have been noticed. Therefore, it is better if you have the opportunity not to check the card for validity immediately after purchasing it.
2) Call cardgolder (card owner) to the bank. Anything can motivate cardholder, from a simple desire to close the card and open a new one, to the realization that he entered the card data into a phishing site.
How are check cards?
This is a microtransaction. If the payment goes through, the card is alive, if it doesn't go through, the card is dead and you will get your money back for it.
In different places they give different times for checking cards, sometimes they can give you one second to check, if you don't have time, then the card is yours, regardless of its validity.
It is advisable to choose places where time is allocated for the check, which will be enough for you to enter.
The process itself.
We bought an CC - the drive was unsuccessful - we checked the card.
We bought an CC - having driven in a successful one - we don't check the card.
Where is the best place to check a card?
It is clear that if you are allocated 1 second to check, then we will check right where we bought it. I can't say that this is the worst option; shops are mainly worried about their reputation and try to prevent checkers from harming the card itself.
If we have a little more time, then there is another way.
Personally, I check cards through the Android application Wolt - food delivery; checking cards with this application does not result in micro-debits. This checker is the safest and cards do not die from it. Similarly, you can check on the American food delivery site grubhub.com.
In no case do we use free checkers outside the store, they can be made to intercept our CC data!!!
If the checker shows that the card is valid, but it does not go through our shop, in 80% of cases this is the card balance.
