BARCODE SCANNING HARDWARE in Apple retail stores
There are many different ways that today’s hottest consumer technology can be used for business applications. While most organizations that use handheld barcode scanning technology still utilize ruggedized, industrial-strength devices from companies like Motorola or Intermec, there is a growing trend to use off-the-shelf consumer technology as a replacement for these often extremely expensive, rugged devices.
For example, in late 2009, Apple retail stores replaced their Windows Mobile-powered devices from Symbol/Motorola with iPod touch devices and a Linea Pro sleeve. The Linea Pro provides laser barcode scanning and magnetic stripe reading to allow Apple Store employees to simply scan a product, swipe a customer’s credit card right from the iPod in their hands, and let the customer be on their way in mere seconds. This article will examine many of the barcode scanning options for organizations looking to take advantage of applications like these.
This article is an update of a review from one year ago, as most of the products have been updated and several new products have been added.
Linea ProThe Linea Pro was popularized as the hardware used in Apple Retail stores to facilitate rapid customer checkout. The Linea Pro is a sleeve for an iPhone or iPod touch, which makes it a single-unit form-factor that is very convenient for many kinds of applications. In addition to providing a moderate level of durability and protection to the iPod touch, it also offers a hot-swappable battery that not only powers the scanner but also serves to keep the iPod fully charged. The Linea Pro has both a 1D/2D barcode scanner and magnetic stripe reader, which makes it perfectly suited for applications like retail point-of-sale where the product can be scanned and the customer’s credit card swiped. A Software Development Kit, or SDK, is provided by the manufacturer, Infinite Peripherals, to give app developers low-level access to scanners and readers to configure settings, trigger the barcode, and receive events for successful scans or swipes. As the first barcode scanner to receive certification from Apple to provide an SDK for low-level access, the Linea Pro is gathering quite a bit of momentum. This is happening in internally developed applications similar to Apple’s deployment and also in several commercial apps and point-of-sale solutions such as LightSpeed Mobile (xsilva.com). The Linea Pro is the perfect device for many types of applications, and although the latest version now supports the iPhone 4/4S and iPod 4th Gen, the Linea Pro does not work with the iPad.
Socket CHS7Socket has been a leader in the barcode scanning accessory market for years, and the CHS-7Xi is a very polished device. Compared to all of the other scanners, the CHS-7Xi feels the most solid and like it was manufactured with the highest quality plastics. In addition to providing the longest battery life of any scanner in this review, the CHS-7Xi also offers both a removable battery and electrical contacts for easily charging in a cradle. The CHS-7Xi has the most intuitive controls for both power and scanning, and it offers both beeps and vibration to signal a successful scan. Additionally, the laser in the CHS-7Xi appears to be brighter than any other reviewed unit and captures scans with more ease than the other units. Since the unit uses the Bluetooth HID profile to connect to the iOS device, it supports the iPhone, iPad, and iPod touch through keyboard emulation. Since the previous review, Socket has been certified by Apple and now provides a low-level SDK for integration into applications, making the CHS-7Xi a serious contender for sophisticated line-of-business applications. The addition of the SDK eliminates the only negative factor in the previous review, making an excellent market-leading scanner for many types of situations where an external scanner is preferred.
Socket has also released the low-end CHS-7C that supports HIDonly (not the SDK) and 1D scanning at a lower price point of $249.
Opticon OPN 2002
(Also known as the Scanfob 2002) ($299, serialio.com)
Opticon OPN 2002The Opticon OPN 2002 (also known as the Scanfob 2002) is the smallest unit covered in the review. The size and form factor make the Scanfob a great unit for carrying around in your pocket for easy scanning. It also connects to any iOS 4.x device (iPhone, iPad, or iPod touch) through the Bluetooth HID profile, which gives it keyboard emulation. As mentioned previously, this allows for flexibility as scanning can be used in almost any application, but since it does not offer an SDK it is more difficult to build rich custom line-of-business applications that use the scanner. The device does have its quirks. For instance, it does not have a power button to turn it off. It will turn itself off after a period of inactivity, but since it connects to the iOS device using the Bluetooth keyboard profile, the keyboard on the iOS device is not visible while the device is connected. The company did provide a scannable setting that converts the small button (normally the button for pairing) into a keyboard toggle switch. Even with its idiosyncrasies, Scanfob is a great unit for many types of applications, and comes in as the least expensive scanner hardware covered in this review.
KDC 300iWhile the KoamTac KDC300i is the most expensive scanner I reviewed, it also the most feature-rich and flexible. It is the only Bluetooth-based scanner that has been certified by Apple and is therefore able to offer an SDK. As the only Apple-certified scanner with an SDK that supports the iPhone and iPad, it is currently the only option for solutions that need this requirement. Beyond that, it has quite a few very unique features like an LED display that can be programmed using the SDK. It also has a programmable firmware that can run standalone applications that you can download to a device in a batch process. This is a very appealing feature for many iPad-based uses, where the maneuverability of a user holding an iPad in one hand with the scanner in the other is questionable. This would allow users to scan a sequence of barcodes, either disconnected from the device for a batch download or connected to the iOS device via Bluetooth, and use the screen on the KDC300i as the user interface for feedback and interaction. For rich line-of-business applications and deployments that require powerful features, the KoamTac is an excellent device, even if it is the most expensive.
Mobilogics iScanA new addition since the previous barcode scanner review, the iScan is certainly the most innovative new product that I had the opportunity to review. As an Apple-certified device that is quickly and easily attached to any iPhone, iPad, or iPod touch, the iScan opens the door for many new types of barcode scanning uses with iOS devices. Add on the very low price combined with a powerful SDK, the iScan has the potential to rapidly gain market share for many consumer-grade and enterprise-class, line-of-business solutions. While the device feels quite solid and sturdily built, it is not nearly as rugged as some of the other solutions on the market. I can see the dongle easily breaking off if the device it is attached to is dropped on the floor. Bottom-line, the iScan is a very innovative and potentially game changing iOS accessory.
Mobilogics iPDT380Mobilogics iPDT380 is an Apple certified accessory for the iPod touch, and includes an SDK for deep application integration. In fact, the iPDT380 uses the same SDK as the iScan, also from Mobilogics, which allows for flexible applications to be built that support both scanner devices automatically. The construction is adequate, but feels a little flimsy, especially compared to the very solid-feeling construction of the iScan unit, although the inexpensive price more than makes up for that shortcoming. The iPDT380 works with the iPod touch (2nd and 3rd gen) but not the iPhone or iPad.
CipherLab 1660New since the last review, CipherLab has introduced the 1660 with support for iOS 4+ devices. While somewhat larger than some of the other external Bluetooth scanners, the CipherLab 1660 is a solid barcode scanner in both construction and functionality. It does not have an SDK, so it only supports keyboard emulation via the Bluetooth HID profile. One interesting feature of this device is the use of two AAA batteries to the power the unit. While many users will certainly prefer a rechargeable battery pack, some users may appreciate the ability to easily and quickly replace the batteries.
redlaser sdkDownloaded over 4 million times, the RedLaser iPhone app (free, app2.me/4259) is one of the most popular paid apps in the App Store. It uses the camera in the iPhone to optically recognize the barcode on a product and then automatically performs searches to allow for easy comparison shopping. The RedLaser SDK gives other app developers the ability to use the same camera-based barcode scanning technology in their own apps, either with custom in-house enterprise apps or with apps distributed through the App Store. Users of applications that require rapid, sequential scanning will find that for intensive scanning, a laser-based scanner is much easier to use than the optical camera-based scanner provided by RedLaser. While a very powerful and simple way to add scanning capability to almost any app, RedLaser was acquired by eBay in 2010, so it’s not entirely clear if eBay is dedicated to long-term support of the SDK for enterprise line-of-business use. RedLaser did not respond when asked if they were planning to add support for other barcode symbologies like Code39 and Code128. Those other symbologies would be required for many serious line-of-business applications outside of a purely retail or inventory context that uses only UPC/EAN. With the exception of these concerns, if your application only needs to support the occasional UPC, EAN, or QR Code scanning on the iPhone, 4th gen iPod touch, or iPad 2, then the RedLaser SDK is an excellent and inexpensive option.
Since many of these scanners have strengths and weaknesses in different areas, there is no single “winner” in the market. There are appropriate applications for each and every one of the barcode scanners covered here. You should evaluate all the options, weighing the pros and cons for your particular situation. You should also conduct a pilot with more than one option, if possible.
That being said, several devices are clear leaders in the marketplace, based on price, quality, and capabilities. The Linea Pro is becoming a very popular device in retail environments where a single device is preferred, and the Socket CHS-7Xi is also quite popular for users that prefer an external Bluetooth scanner. Additionally, the iScan holds a very significant amount of promise for many types of interesting uses, as it is the only certified scanner that currently physically attaches to the iPad.
While Microsoft has had a virtual monopoly on barcode scanning solutions with Windows CE and Windows Mobile for nearly a decade, Apple is now able to make a serious play in this space with this line-up of scanning accessories. Since this is an area that is going to only evolve further and attract additional competition, the coverage of this area of the market will likely be an on-going effort for future articles and reviews. In the meantime, if your organization already has or is considering deploying an iOS-based scanning solution, I would love to hear from you about your experiences with the different products on the market.
