Bar code is tried and tested technologythe no-brainer choice for identifying items in the supply chain. Yes, it does have short comings in that applying it means that everything has to be in line of sight because light is used to capture and read the bar code. But as goods are handled either by humans or machines, the goods are always visible, as are their labelslabelling standards mean that it is virtually impossible to not see the label and its bar code. This means that some form of scanner is usedthe range of available technology is broadeither by an operator wielding a hand-held device or by a machine-mounted or fixed-position scanner.
Beyond the bar code is RFID (radio frequency identification) where a chip within a tag carries information and is read using radio waves. This is a relatively robust data carrying technology and is seen by some as a successor to bar code but in reality it is a complementary technology. It does much the same thing as far as identification goes, but it does offer the opportunity to carry more datahowever there is an argument for not carrying data in a tag but to keep it secure within a database. But, we could go on forever about what and not to do with RFID tags and the wise would do well to talk to their supply chain software vendors to find out if RFID is something they can integrate with their existing systems.
So lets get back to the hardware and take a look at a few examples of the different kinds of technologies available.
Scanners for all reasons
Bar code scanners are very sophisticated devices these days. Functionality and reliability is extremely important but designergonomics in particularis right up there at the top of the requirements list too. And in response to user requirements it seems to me that the majority of scanner vendors have left nothing to chance in presenting excellent value products.
Metrologics VoyagerBT is a recent example of a Bluetooth-enabled hand held scanner. I saw one at a show and was impressed with its overall design, particularly its shape and balance, plus it offers Bluetooth as a communications interface. Bluetooth is becoming important for connectivity with so many other products taking it on board including printers, hand held computers, etc.
Datalogics scanner design and manufacturing divisions are prolific. Weve seen the Gryphon, Heron and FireScan all hitting the market of late. These are less radical in their form factors than the VoyagerBT, but are nevertheless fully functional products.
Hand Held Products draws on the know-how of its Welch Allyn roots for bar code scanning innovation. Its IMAGETEAM series goes right across the range from linear to 2D readingwhich utilises its class-leading imaging technology that is now threatening laser-based devices for functionality and future-proofing.
Symbol Technologies is notable for its technology. Symbol is also responsible for taking a lead in bringing superb ergonomic design to the AIDC market and is the first company to have delivered a boutique quality product nine years ago with its LS4000 for which it won a Silver award in the 1996 Industrial Design Excellence Awards (IDEA), co-sponsored by BusinessWeek and the Industrial Designers Society of America (IDSA).
Intermec offers good scanning products tooits ScanPlus Vista and Sabre range are notable. They look like they will do exactly what they are designed to do and this encourages confidence in the equipment and you just want to pick the devices up and scan with them.
Computing in the hand
Portable computing devices are the champions in the productivity tools world and their evolution over the last decade has been rapid. No longer confined to simple picking operations, hand helds are being deployed usefully higher up the chain of operational command allowing managers to make decisions more quickly and with greater confidence.
The products shown here are just a snap shot of what you can buy today. Whether its a PDA, industrial hand held or lightweight data collection terminal there is sure to be a tool to fit the job.
