Our Products / RFID Hardware, Barcode Hardware

Definition.

The hardware that we supply generally falls into three categories: handheld computers; barcode equipment (readers and printers); and RFID equipment (portable and static readers). The handheld computers usually include a barcode scanner or RFID reader.

Range of products.

SageData supply hardware from many different manufacturers. We generally focus on handheld computers, and RFID and barcode specific hardware, but will supply servers and desktop computers if they are part of a system. We have a close relationship with some of the top vendors, and often participate in the initial field testing of new products.

Handheld units.

This is the basic workhorse for many of our systems. The standard products include a screen (usually quarter VGA), keyboard, processor, and memory. Most units today use a colour, touch sensitive screen. Most are used with barcodes, and an integrated barcode scanner can be configured to read most standard barcode symbologies, including 2D, or stacked barcodes. These devices place great emphasis on robust construction and long battery life. Mobile, handheld computers can be broken down into two categories: batch and RF.

Batch Mode mobile handheld computers.

These units are intended to operate autonomously - independent of all other support systems. Data is loaded to the machine. During use, that data can be referenced for confirmation or direction. At the conclusion of the mission, information is moved back to the central system. Key elements include data security (protection from loss of data), and the requirement to synchronise copies of a database which may have been independently updated.

More generic information on handheld computers

RF Mode mobile handheld computers.

These units are set up to operate in conjunction with a central server. In operation, they pass the users' request back to that central server, and display the servers' response to the user. Use of these units is restricted to the area covered by the radio system - usually some hundreds of feet in any given direction. Benefits include ease of use and immediate access to current data.

RFID technology

SageData have systems operating in LF, HF and UHF ranges.
We use handheld computers with integrated RFID readers for LF applications such as animal tracking.
We use HF technology with shelf readers and mobile readers, for asset management, and for reading wristbands, such as those used in patient care.
We have UHF solutions with mobile RFID readers that can be used for asset management, file tracking, and control of consumables.
There are very rapid advances in the field of RFID, so contact SageData directly for the latest information.

Barcode Technology

Hardware includes readers and printers.

Barcode readers aka barcode scanners.

Sometimes called wedge readers, tethered scanners, barcode scanners or presentation scanners, these devices are connected to a conventional Windows machine (either desktop or notebook) and enable that machine to read information presented in barcode format.

What is a "wedge reader"?

When first introduced several years ago, barcode scanners or readers often connected to the desktop computer by being "inserted" between the keyboard and system unit. The keyboard connected to one cable on the wedge reader, and another cable from the reader connected to the keyboard connector on the desktop computer. The scanner was "wedged in" between the system unit and its keyboard.
Now, with the advent of USB, most readers connect directly through the USB port, and true "wedge" readers are little used - though the name still lingers on...
Some configuration of the USB readers may be required.

What is a "presentation scanner"?

Most readers are operated manually - the user picks them up and points at a barcode. Sometimes it is more convenient to leave the scanner in place, and present the barcode to the reader. The reader in this case is called a presentation scanner, as the barcode is "presented" to the scanner. This set up is particularly useful in a manufacturing environment, where a worker may be handling an item, and needs to identify that item by scanning a barcode.

Barcode Printing.

Barcode printing is very difficult. But it is also very easy.
By this we mean that it is very easy to do, if you follow carefully a long list of pre-requisites. But very easy to get wrong if you miss a single step.

Barcode printers.

The first step is to buy the right printer. Many printers on the market today are far from robust. They are difficult to get working, and easily fall out of adjustment. We recommend investment in an industrial quality printer.

Barcode printing software.

Having selected the printer, the application is the next issue. The application must be capable of controlling the printer, or a separate software application is required. These packages can be extremely complex and difficult to set up.

Barcode printing supplies, labels and ribbons.

After that, there is the selection of supplies, label stock and ribbons. Plenty of scope for error there.

Barcode printing label design.

And finally, the design of the labels themselves. Did you get the quiet zone right?

The barcode registry.

One of the key administrative challenges is that of keeping a registry of numbers issued. We have helped several clients who have ended up with overlapping ranges (and logical chaos) in their systems. SageData provides a registry for our clients. They need only order "another ten thousand of the small ones", and we will ensure that the new sequence will be contiguous, and not overlapping.

Barcode printing - summary.

None of these issues is insurmountable. But there is plenty to get wrong. Make sure you work with a barcode professional, before selecting and setting up your barcode printing system.
