Be Careful When Scanning Unknown QR Codes

ByEmily Dolloff

QR codes, those square, blocky codes you scan with your iPhone’s camera to load a Web page, have become ubiquitous. So much so that we seldom pause before scanning any QR code we see. But if you think about it, that’s the same as clicking random links in emails or texts, which is a terrible idea from a security perspective. “Quishing” (QR code phishing) isn’t commonplace yet, but some sources say there are thousands of cases per month. To avoid falling victim to a quishing scam, only scan QR codes from trusted sources, try to verify what a code will do once scanned, and evaluate the yellow URL preview Safari provides (when using other browsers, all you see is Open in Browser Name). Finally, always install iOS security updates promptly because they often address vulnerabilities that could be exploited with malicious data.

Social Media: QR codes—those blocky squares you scan with your iPhone camera—are an easy way to open a Web page. Unfortunately, scammers also use them to trick people into visiting malicious websites, so read our tip about scanning these codes safely.

  • CES Random Thoughts

    I talked a bit about the big Consumer Electronics Show last week and it is rapidly fading in the rearview mirror. I have gone to this show every year for the past decade or more. We actually exhibited our Chill Pill speakers and Hammerhead products at one CES but mostly I have come as a “buyer” to look for new products and trends.

    The Las Vegas convention center is a gigantic venue and the CES show spills out into the parking lot in front but also into some of the surrounding hotels and resorts. The Sands convention center was the second largest and housed some of the more interesting booths. This was the location for 3D printing, health care, fitness, home automation, robots and drones. There were sophisticated baby monitors, constant reporting thermometers, implanted blood glucose monitors and even a company that sold wireless sensors that monitor your soil’s nutrients and moisture. Home automation was huge with several competing standards vying to challenge Apple’s HomeKit. This year more companies were showing HomeKit compatible products so I think that Apple’s vision of your interconnected home is not far off.

    There are lots of ways to move from the Sands over to the LVCC but the best way is the free buses offered by CES. Cabs and the monorail are possible but the buses seem to be the fastest and they are free and comfortable. For me it was a great way to rest my weary feet for a few minutes before going to the other venue to continue walking through the crowds. At the convention center there are three main halls and the international pavilion over at the Westgate (formerly, Hilton). The Center hall is dominated by the big guys with gigantic booths for Samsung, Intel, LG and others. Those booths are usually mobbed so I quickly walked through to check out the TVs and moved on. The North Hall is where the iLounge was born and products for iPad and iPhone dominate that section. The biggest part of the North Hall, however, was the Auto section with concept cars being shown my several manufacturers including Ford, Audi, Mercedes and new electric car upstart Faraday.

    In the past several years the iLounge area and the international area were dominated by all sorts of cases for iPhones and iPads. This year there were a few in each section but cases were definitely not the dominate category. Over at the international pavilion there were lots of hover boards but unlike previous years, demos of the scooters were restricted to the booth area. Nevertheless, all sorts of scooters were being shown. I searched for interesting USB-C products and found some hubs that were not quite ready for prime time and a bunch of cables. I did see the USB-C displays that incorporate a hub and that could be the real solution for the office set-up for the USB-C equipped MacBook.

    I never seem to be able to coordinate my meetings by hall. It seems that I’ll have one meeting in the North Hall, the next in the South Hall and then another back at the hotel. I rode the buses a lot and got to see the whole show floor that way.

    I did find some interesting products that we may add to our offerings, and had some great meetings so it was worthwhile to visit this show that is a window on future technology.

  • The Most Profit Ever in a Single Quarter

    Apple posted record earnings and profit for the holiday quarter disappointing those analysts that predicted less than stellar results. Of course, the realistic guidance for the next quarter sent Apple stock plummeting while those same analysts maintain a price target that is $40-50 higher than the current price of the stock. Okay, so Apple’s profit and revenue were all time records for the company but the remarkable tidbit is that no public corporation ever has posted that much profit in a single quarter. Let’s see how Apple did that.

    First of all, Apple sold 74.8 million iPhones in the quarter. Not too shabby and that revenue is nearly 70% of Apple’s total. The average sales price (ASP) for the iPhone was up to $691 which also led to slightly higher gross margin. To put that is some perspective that is an average of 34,000 iPhones sold per hour 24/7 for 13 weeks.

    They finished the quarter with about $215 billion in cash which represents about $39/share. Macs sales were down a bit at 5.3 million units and the iPad continues to do moderate in sales with sales dropping year on year from 21.4 million units to 16.1 million units.

    Currency “headwinds” have caused some of these results to be muted. With the exceptionally strong dollar it is more difficult to export US goods and sales suffer a bit. The Euro and British Pound were down double digits and the Canadian and Australian dollars were down 20% or more. It gets worse. The Russian Ruble is down by 50% and Brazilian Real is down 40%. Apple estimated that if it were not for these global currency fluctuations that their revenue would have been over $80 billion representing an 8% increase. But despite those headwinds, Apple posted their best quarter ever.

    Other high points were service revenue which was the highest ever at over $6 billion. Wow, $6 billion in just iTunes, App store and a few other things. That is more revenue that quite a few well known companies and a 24% growth year over year. Other products which include the Apple TV, Beats and Apple Watch also were strong with $4.5 Billion in sales.

    In another milestone that just points to the success of the services side of Apple’s business Tim Cook announced that they now calculate that there are more than 1 billion Apple devices in use worldwide which is up 25% year over year. That is simply incredible considering that there are only 7.4 billion people on the planet!

    What sent Apple stock down was Apple’s realistic prediction that iPhones sales in their 2nd fiscal quarter would decline year over year by as much as 15-20%. Last year’s 2nd quarter was strong because of supply issues that moved some revenue from the 1st to 2nd quarter and the impact of the global currency situation has caused some price adjustments. Apple remains very bullish on the iPhone market and pointed to the fact that in China over 50% of the iPhones sold were to people buying their first iPhone. Apple pointed out that the growth of the middle class in China is unprecedented with the middle class comprising about 50 million people in 2010 and now it is projected to be $500,000,000 by 2020.

    Even if Apple sells “only” the 40-45 million iPhones in this quarter that would still be more revenue that most companies earn overall in a single quarter. To put this in perspective, Apple books more revenue at strong margins, than Amazon, Facebook, Google or Microsoft generate from all of their operations.

    All in all the financial results that Apple announced were an incredible testament to the quality and innovation of Apple products and of a company doing things right. Congratulations to the entire Apple team!
