Samsung Pay just killed its best feature on the S21

Samsung has removed MST, or magnetic secure transmission, from the US editions of the Galaxy S21 phone and all future Galaxy phones sold in the US. This feature let you pay at almost any terminal, even ones that don’t support NFC or mobile payments.

    Disappointed. In my country, there are many stores with the old card readers, I used to surprise some people while paying with my Samsung.

    I won’t forget one person asked to me; “what are you trying to do? Are you trying to hacked it?” So funny.

    It was awesome but such a US-only problem. In the Netherlands I haven’t paid by card in years, it’s been all NFC and my phone (or watch with a proxy). Banks have supported it on phones since 2015 and now even random parking meters support nfc payments.
    Magnetic swipes have also been blocked for over a decade in europe since it’s just unsafe, so it’s chips and nfc all the way now.

    I’ve loved being able to use the MST ability for years! I shop local often, which also means small biz in many cases. Farmstands, local eateries, food trucks, pop ups….. all places that would say “oh we don’t support phone pay” to which I’d say, “I’ll bet u do with mine !” It really helped small & local biz! I’m disappointed that they’d remove this feature! 😔

    Especially considering that you dont have to enter in a password if your phone is unlocked with google pay.

    Because of MST I made myself use samsung pay, but on my LGv35 i used google pay and that was just so much more ‘user friendly’ for lack of a better word.

    I’m gonna be that guy here- The problem isn’t with Samsung, the problem is with store owners unwilling to upgrade their point of sale technology to support as many payment options as possible. Why would you not want to get on board with NFC as soon as possible? Contrary to what this lady says in the video, it is NOT a large investment to upgrade your systems to support it at all, hardware included…

      I guess “agree to disagree”. Many smaller retailers have little-to-no “extra” funds to invest in infrastructure upgrades; heck, they’re taking a beating when they have to add on the %age for every credit/debit transaction!

      @Tim Sawyer The question is what makes the situation in the US this stubborn to adopt NFC terminals..I understand if contactless was considered bleeding edge technology. But this is common place in the vast majority of the world.

      I don’t know how the US structured it, but up here in Canada EVERY merchant has an NFC terminal for the past 10 years. Adoption was almost completely driven by the liability shift to EMV cards and contactless payment was just given as a freebie as the vast majority of EMV cards have an imbedded contactless circuitry (Actually more often than not, most people up here use contactless with their actual card. contactless phone payments is rarely used even though they are intercompatiable .

      Assuming that the US liability shift went smoothly…Do you guys actually have EMV terminals but don’t take contactless? It just seems bizarre considering the vast majority of the cost would be the EMV tech, not the rfid radios needed for contactless payment.

      @skifree well, I’m not a retailer, but we are decidedly free-market-based, so we don’t have a lot of incentives from the government (e.g., subsidies) to upgrade, like I THINK some other countries have. Even mom-and-pop stores have to purchase equipment, and many took a chance just to buy the “cheap” stuff to even allow credit card purchases in the first place. And like I said, they’re taking a hit (3% on every purchase, if I’m not mistaken) every time they allow it, but feel like they have to just to stay in business. Also, NFC doesn’t seem cutting-edge to many, but in rural areas there’s just not much demand for it, so retailers don’t offer it, so there’s not much demand for it, so… (see what I’m saying?). Therefore, it’s a pretty sizable expenditure to upgrade to a technology that may not even offer (at least not yet) much financial return. So, it’s just not as easy as folks think when they ask, “why don’t the business owners just…?” I hope that helps clarify things.

      @Tim Sawyer As I asked before, didn’t you guys have a liability shift? that’s reason enough for the rest of the world to upgrade.

      My point was, portraying new terminal upgrades as access to new “features” and if there is “demand for the new feature” is NOT how the rest of the world got nfc terminals. We got them because Credit Card companies basically mandated the use of new terminals and NFC just so happens to be getting cheap to where they just “came bundled” into them. Or in other words, the CC companies basically said “the new terminals are safer and they cut down on fraud…so use them and if we find out that you fraud was committed at your businesses and it was charged on magnetic stripe, then we come after you for the money”. It was never about features or demand, just the fear of the CC companies and adopting their new policies to take new terminals. The NFC and other features just came as bonus because it costs basically next to nothing to add them when you are committed to getting an EMV terminal anyways.

      @skifree interesting — I did not know this! But then again, like I said, I’m not a retailer. Why the banks would behave one way in the US and another way elsewhere, I don’t get that either (unless maybe it’s the way our regulatory system works?). (Or maybe they aren’t that different, and I just don’t understand how it all works.) All I really know about this whole situation is that many retailers can’t just afford to go out and get new stuff, which appears to be the way they would have to obtain NFC tech.

    I think Apple and Google saw that MST, while useful five years ago, was not worth investing in because NFC would become the dominant payment option in short time… and they were right. Back then I kind of wanted MST on my iPhone but I quickly found that most of the time I could use NFC at most places that I shopped. Now, with Apple Pay on the Apple Watch, I don’t even need my iPhone and the process is much faster than using my iPhone!

    TOTALLY agree! MST is the MAIN reason my wife and I use Samsung Pay, and a BIG reason we’ve been faithful to Samsung phones. Some retailers (e.g., Walmart, I think in order to push their proprietary Walmart Pay system) have switched to systems that made Samsung Pay no longer work, or at least not consistently, but in the rural south there are still a LOT of places (like the article said, mainly mom and pop stores) that don’t offer contactless payment, so MST is still often the only way to pay with phones. I’ll keep my Note 10+ until it dies, (and my wife her S9+), I guess, but now there’s definitely one less BIG reason to buy Samsung. So sad! 😢

    I couldn’t agree with you more
    1. I have loved MST and the fact that everyone was shocked when it worked. It was my favorite bragging feature when iPhone users were around.
    2. There are nowhere near enough contactless payments. Can’t believe I have to go back to carrying around a credit card if I upgrade.
    3. We’re in the middle of a pandemic…keep the feature!
    4. I don’t feel like I get much from the Samsung pay points.

    Currently have an S9+, I may upgrade to the S20 instead of the S21. When I lose MST, I’m going to google pay. Really really disappointed Samsung cut this feature. They should have held out for another 5 years before phasing it out.

    MST was a deciding factor for me when it originally came out. I was looking at different options, but having the ability to have contactless pay nearly everywhere before NFC was common was huge. When I learned that they were doing away with MST on the S21 line I seriously considered jumping to Apple for the first time in a very long time. In the end the camera on the S21 Ultra was the deciding factor for me this generation, but with phones being so good regardless of brand now (IMO) I don’t understand the rationale behind cutting such a differentiating feature. As it is, I don’t have any meaningful incentive to continue to use Samsung Pay. I would take an unscientific guess that the people who are in the android ecosystem mainly use Google Pay with Samsung user being the exception up until now. I don’t see that being the case anymore.

    This really shouldn’t come as any surprise. As more newer, bigger and better features come along, older features go the way of the dinosaur. I’m just willing to bet that has companies start going down the privacy road that Apple is currently going we will lose other features. I’m not saying that privacy is a bad thing, I actually value my privacy. What I am saying is that as that becomes the focus of the future smart phone business other lesser used features will fall by the wayside
