How Do They Know?

Yesterday, our credit card company called to let us know Hubby's card was compromised. Someone attempted to buy hair product and yoga gear. These two transactions were flagged as suspicious. We didn't try to buy these things, so I'm thankful. But I might buy things like that. So how do they know?

I think it's just basing it off your usual purchases. It's happened to me a few times and I think once was actually not me or my husband. I would rather them check than have to go through change of life to get the charge off of me later or worse have to go through stolen identity loopholes.

Oh yes, I'm glad they caught it. I do buy clothes online occasionally, but only from one or two specific sites. And I've never bought hair products online. Though it seems a normal enough purchase.

@paigea Sometimes normal can be weird depending on what you usually do.

There is some sort of algorithm that is employed that recognizes unusual activity, and this must have flagged as unusual activity.

It's interesting as they are clothes and hair products. I've never bought any personal care products online, but clothes, I have. Maybe because both items were exactly the same amount?

@porwest Their vigilance did backfire once also. I'll post about that sometime.

@paigea That could be. It is amazing what they can detect and how quickly they can detect it.

This would be because whoever used your husband's credit card, might have in put the wrong PIN . I am just guessing this. What happens is when you input a wrong PIN, or even if you do a successful transaction you always get an SMS letting you know that something has been purchased using your credit card. Or even if we use a debit card, the same kind of SMS is sent by the bank, just for our confirmation. This helps to reduce the number of frauds taking place around. I can think of only these two possibilities.

@paigea Now even I am surprised to know that the title you have given to this discussion "how do they know", if quite apt. Initially when I read your question I was under the impression that the card was missing and that's why you got the call that there was a transaction. But your second reply clears the air for me. And this really is quite an excellent method to let you know that the card has been compromised. I think those credit card people will be the best ones to talk how they made out that the card had been compromised. I am also perplexed and trying to find out any logic behind this call. Of course, we can also login to the system and check out the transactions. But it depends on what service the particular app provides. I am surprised you don't have such a system of getting an SMS when you get a debit or credit in your bank account or if you make a purchase and the money is spent. But anyway if the system doesn't exist in your place, it means still the entire sales - purchase system is working fine for you. And you get to know all your transactions by logining into your system.

@abhi_bangal Yes, I just have to remind myself to do it.

His card wasn't missing but still got used somehow. That is a good system to get a text when a purchase is made. We do not have that service. We can login to our account and look at all the transactions.

I rarely get notices like that but once in a while they will ask if I was trying to make a purchase somewhere online and I have the option to say yes or no, that's about all I ever get

I didn't answer the phone. I called them after they left a message and had to go through a big process talking to someone. And Hubby's card is cancelled

Good thing they caught the transactions on your husbands credit card. It is curious that they knew it was fraudulent because those are common items most people would buy.

I meant to add that each of those transactions were for the exact same amount. Maybe that was suspicious? Or maybe they just know from past experience that that's a fraudulent company?

I’m glad they caught it. My credit card card company once caught someone trying to buy something at a Walmart Neighborhood Market, where I shop all the time. Only it was one In Arkansas, and I live in Oklahoma.

It may have been the IP or mac address from where they purchased, if it was online.

I think sometimes it is the location items get purchased from. I have had mine call me when it was right down the road and some place to go to often so I really don't know for sure what they base it on. Sometimes it is a pain, we had our hotel declined when we were on vacation, I had to call them and they said I should have told them I was on vacation.

If you haven't bought it in the past, it looked suspicious to them, flagged it, and notified you. I'm glad they did.

I'm glad too. The hair products I sort of get, I have never bought personal care products online. Yoga gear is something I might buy. This was Hubby's card though. He buys products in the personal care category and he might buy yoga gear as a gift for me.

Good that they could make out the suspicious transactions and alert you. I am not that expert, buy it seems that there are algorithms that can detect suspicious transactions.

My latest debit disaster was caused by a nasty idiot on the Web signing up for a dating service. Wish I were joking. Due to that incident I had some late fees from at least one service cause my debit card was out of action for a bit

Where the purchases in a town a long way from you? That might be a reason for the banks to be on the alert. It has happened to us but someone in England tried to make a purchase. That's a long way from where we are.

It is good that they blocked the transactions. They would have internal safety measures to identify threats.

I hope you have verified that this is called from the actual credit card company and not from a scam person. There are different ways, people are scamming by stating they are calling from credit company , bank etc. If you have not provided any sensitive information and they never asked for, then it is all fine. As far as the credit company blocking a transaction, they are capable of doing the same.However, perhaps the authenticity of the website or the payment gate would have caught attention of their systems and blocked. I have not experienced any blocking of purchases .However, they used to verify whenever they saw big purchases. So, no guesses from me on how they did the same.

Hubby didn't answer the phone when they called. I called the number on the credit card from my phone. His card was already blocked before they called because he was trying to use it. A new card is on the way.
