Motorola Sled Reader Adds Low-Cost RFID Functionality to Mobile Computers
The new EPC Gen 2 UHF device locks onto Motorola Solution's existing handheld computers, enabling users to upgrade their devices to support RFID for $1,995.
Nov 21, 2013—
A variety of companies, ranging from mines to bakeries, are currently trialing a new, low-cost Motorola Solutions EPC Gen 2 ultrahigh-frequency (UHF) RFID reader in the form of a sled that snaps onto a Motorola mobile computer with a built-in bar-code scanner. For Motorola Solutions, the RFD5500 sled reader—which fits onto the company's existing MC55, MC65 and MC67 family of handheld computers—represents the first new RFID-based product the firm has offered in many years.
The company's aim, says PV Subramanian, Motorola's senior manager of RFID product management, is to seed radio frequency identification in places in which the technology has not yet made headway—either due to cost constraints, or to businesses' reluctance to start using new hardware and a new software platform.
According to Motorola, the solution represents a low-cost alternative to buying a new RFID handheld from the company, such as its MC3190-Z or MC9190-Z models. Motorola's handheld readers typically cost about twice the price of the new RFD5500 sled. Not only is it lower in cost, but it also enables companies to continue using their existing bar-code-based tracking systems with the added functionality of RFID, requiring very little staff retraining to operate.
More than one million Motorola MC 55, MC65 and MC67 mobile computers are already in use worldwide, enabling users to scan bar codes of goods for sale, as well as track assets. With the recent surge in item-level RFID-tagging in the retail sector, the company expected a large demand for sled readers for attachment to stores' existing handheld computers. However, Subramanian says, he has been surprised by the broad variety of use cases in which the sled is already being utilized. For instance, he notes, there is keen interest from firms using returnable transport items (RTI), such as totes or pallets. By employing RFID to track the reusable containers, a business can also track such details as deliveries or the locations of goods loaded in or on the containers.
For example, a large bakery company in the United States is presently testing the sleds attached to their existing MC55 devices, in order to determine whether they can obtain valuable information about the movements of their returnable plastic trays, both when being delivered full to customers and when being picked up empty.
Containers often end up missing in the baking industry, in which fast-paced deliveries are made each morning to everything from small delis to supermarkets, with quantities of trays ranging from one or two (for the smallest businesses) to hundreds daily (for the largest). Ensuring that every tray is accounted for is nearly impossible, Motorola explains. The large bakery, which has asked to remain unnamed, already had Motorola handheld computers, but found it too time-consuming to use them to scan each tray's bar code. Consequently, data about each tray was not available in real time. With the sled reader, drivers can now do much more. Upon delivering a stack of trays to a customer, a driver simply holds the reader in front of the stack, captures all unique ID numbers and then inputs data into the software, thereby indicating that the customer has received those trays. If a stack of empty trays is picked up, the driver can input that information directly into the handheld as well, after interrogating the tags.
