Choosing the Right Technology for Your Application


In addition to selecting the right automatic identification technology, there are over 5,000 different automatic data collection related devices on the market. So, how do you choose? Give us a call. We'll help you determine the solutions that best meet your needs and budget!


Radio Frequency Transmission of Data


RF transmission provides "real time" data entry without using a tethered scanner. Many applications require the user be too far from a computer terminal to use a bar code scanner cabled to the terminal (such as warehouse and shipping applications). In these cases, data can be collected into a handheld data collection unit, then downloaded at regular intervals to the computer; this is batch data entry.



If data is needed "real time" (instantaneously), a bar code scanner equipped with a radio frequency transmitter can be used. The radio waves are picked up by the RF receiver connected to the computer. All kinds of devices are equipped with RF, including bar code scanners, handheld data collection terminals, truck-mounted terminals, and PCM/CIA cards.


Radio Frequency Identification Technology


RFID is used to automatically identify, categorize, and locate people and assets over relatively short distances (a few inches to hundreds of feet). RFID labels are known as "tags" or "transponders". They contain information ranging from an ID number to 128K bytes. Then an RFID "interrogator" is used to send out an RF signal which "wakes up" the tag, and the tag transmits information back to the interrogator via RF.



At this point, the interrogator can write new information to the tag. This enables the user to alter the information stored in the tag from a distance. Interrogators can be networked together to provide nearly unlimited coverage for a system.


RFID is being used for:

  • Identifying objects in harsh environments
  • WIP tracking of items through the manufacturing cycle
  • Personal identification/access control
  • Identifying vehicles on roadways, as well as for automatic toll collection
  • Tracking rail cars so railroads have real-time location data of their rail cars
  • Identifying trucks for trucking companies and intermodal container carriers
  • Providing automated inventory and location of assets

Voice Data Collection and Operator Direction


Voice is one of the most exciting new technologies we've seen. This voice technology is far more sophisticated than the PC-based packages big computer retailers sell. In an era of declining literacy in English, and rising need for eyes- and hands-free data collection and operation instructions, it offers a real solution. Each voice unit has its own voice board and each operator has their own voice file.



So, one operator can speak Vietnamese, another Tagalog, another Spanish, and others English and all perform the same work! Voice also works in tandem with bar code scanning. Voice can be used for almost every application a handheld data collection terminal is used.


Voice, Computers, Printers, and Bar Code Scanners on One Network


Imagine a wireless phone that's also a bar code scanner. Imagine your computer and printer connected to the server via a small RF transmitter instead of a cabled connection.


Imagine this all operates over ONE network. Interested? Give us a call and we'll tell you how real this is!
