CISProMobile is a radio frequency identification (RFID) product that integrates with the CISPro Chemical Inventory System. It is offered as a package that includes the printer, the pre-programmed handheld PDA, and a Bluetooth-enabled wireless RFID reader. Unlike barcoding, which uses optical systems to transfer information from the printed coded label to the barcode scanner, RFID reading can be done remotely and does not require direct contact or line of sight between the item and the reader. The antenna, the transceiver and the decoder are incorporated into an integrated handheld reader. When the reader detects the RFID tag, it decodes the data encoded in the tag's integrated circuit, and the data is passed to the PDA for processing.
