Handheld computers are highly portable terminal devices used for reading and collecting data concerning items. In recent years, not only can they read barcodes and 2D codes but they are capable of optical character recognition (OCR) to read characters directly marked on products and parts, such as lot numbers and serial numbers, as well as expiration dates. Unlike handheld code readers used for reading codes only, handheld computers have a CPU and LCD screen built into the body. They can be used for various applications through the use of business programs, as well as for information browsing and alert display. Typical applications are inventory, work-in-progress, and process management of parts, products, and raw materials. Handheld computers must provide excellent operability, durability, waterproofing, and dust proofing to enable their use in various worksites in the manufacturing, logistics, retail, and wholesale fields.

Benefits of Mobile Computers / Handheld Computers

Barcodes, 2D codes, and characters on product slips, instruction sheets, products, and parts can be instantaneously read, converted into data, and recorded.

It is also possible to record additional information such as the time of reading, which greatly improves the efficiency of warehousing and process management.
Some types of handheld computers can use optical character recognition (OCR) to acquire characters, such as serial numbers and lot numbers directly marked on products and parts, as well as expiration dates. This is effective for both reducing man-hours and preventing careless mistakes during the management of products and parts with no barcodes / 2D codes, which were impossible through visual check and manual entry.

After reading one code, handheld computers can read the information linked with the code automatically or can export information automatically to a specified row/column in Excel or other software.

The data read with handheld computers are saved automatically. To make it easier to collect data from each transaction, the saving format can be determined in advance, which reduces the number of work-hours spent on data management.
Some operation-specific applications may require labor and cost for programming. Since handheld computers allow the setting of business applications without programming, they can save development costs and the time and labor required before the start of the operation.

Handheld computers capable of wireless connection allow readout data to be applied to the system in real-time.

With paper-based aggregation, the overall results can be checked only after operations such as inventory and warehousing are complete and the data is entered into a PC. On the other hand, with wireless type handheld computers, the results can be transmitted as the work is being performed, so the status can be checked in real-time. This enables management with no time lag, which was impossible through paper-based aggregation. This prevents careless mistakes when data is created from paper or inventory is made by several workers. It also prevents mixed-up information in workplaces where the inventory changes frequently.

Handheld Computer Case Studies


Handheld computers enhance the efficiency of matching delivery statements and cargo during receiving inspection and recording the inspection results at warehouses and distribution centers.

Inventory Managemet

Inventory management refers to maintaining the optimal number of items to match the situation.
there are many things subject to inventory management, it is effective to use an inventory management system in which barcodes and 2D codes are affixed to items and handheld mobile computers or similar devices are put to use.

First, read the barcodes for the item and its location (shelf, row, and level), and then enter information such as the quantity to register it. If location management has not been performed, generate barcodes and affix them to the shelves or similar locations. After all the items and locations have been registered, accurate stock management can be performed just by reading the barcodes during warehousing and when moving items. The data from operations such as warehousing and inventory can be checked in real time, which enables appropriate management.

Inspection of receiving goods

During the inspection of receiving goods, the delivered goods and the delivery slip that was sent together with the goods are verified to check that there are no problems with the product numbers and quantities and the goods are inspected for damage and problems in quality. If the inspection of receiving goods is performed visually, it is inevitable that some items be missed or read incorrectly, that the recording of some items in the ledger be forgotten, or that other similar errors occur. Mistakes that occur at this stage will be carried through to shelving and picking and may finally result in erroneous shipments. Handheld mobile computers can be used in this inspection of receiving goods to eliminate the majority of user-caused errors and thereby prevent erroneous shipments.


Traceability is a word coined by combining “trace” and “ability.”

In traceability, the identification symbol used to transfer the information is called the expression pattern, the item on which data is recorded (such as a label or electronic tag) is called the transfer media, and the item such as a paper ledger or PC used to collect and manage data is called the recording media. The easiest traceability method is to write handwritten notes (the expression pattern) on slips (the transfer media) and rewrite this information in a ledger (the recording media). However, this method is a hassle and is inefficient in recording a large amount of information. Hence, handheld mobile computers and similar devices are most commonly used to read barcodes and 2D codes in order to obtain traceability.

Pokayoke (Error-proofing)

Mechanisms for detecting or preventing the generation of defects caused by careless mistakes, which are unavoidable at manufacturing worksites, is referred to as pokayoke (error-proofing).
There are various causes of careless mistakes at manufacturing worksites. Just a few examples are incorrectly reading product numbers, taking the wrong part, making mistakes in the setting of molds and jigs, and making mistakes in the blending of raw materials. Careless mistakes such as these can be prevented by thoroughly performing verification with handheld mobile computers. This section introduces pokayoke (error-proofing) using handheld mobile computers.

Frequently Asked Questions About Mobile Computers / Handheld Computers

Handheld code readers are a type of barcode reader specialized just for reading (scanning) codes. The readout data should be processed with a connected PC, so handheld code readers cannot be used separately from a PC and carried around like handheld computers.
On the other hand, handheld computers have an LCD screen, CPU, and memory built into the body. Programs can be embedded so that not only can they read data but they can also perform other required processing such as checking (displaying), matching, and saving data. Programs can be rewritten depending on the usage or purpose of the work. For example, you can set which of several information pieces obtained from one reading is to be entered automatically into which rows/columns in Excel.

The installation requires a variety of equipment such as a PC or a server to communicate with during operation, a battery that supplies the power and its charger, and a printer used to output data (when required). It is also necessary to develop software to provide system functions and operability that match the usage environment and the purpose. Examples of issues handled by the software include how to aggregate and process data or how to display the aggregated data on a PC screen.
On the other hand, some handheld computers are designed for simple operations by adopting a common platform, using dedicated software to create business programs quickly, and aggregating data as intended with Excel. Hence, it is important to consider the hardware, software, and other items suitable for the purpose, scale, and existing system, prior to installation.

The different handheld computer models have a wide variety of functions to match varying industries and applications. For example, to establish communication with a system within a large warehouse or store, select a type with a built-in wireless LAN interface. To perform work in a limited space, select a Bluetooth-equipped model.
