RFID IN SCM
[attachment=27772]
What RFID is?
Radio-frequency identification (RFID) is an automatic
identification method, relying on storing and remotely
retrieving data using devices called RFID tags or
transponders.
RFID (radio frequency identification) is a technology that
incorporates the use of electromagnetic or electrostatic
coupling in the radio frequency (RF) portion of the
electromagnetic spectrum to uniquely identify an object,
animal, or person.
• An alternative to bar code.
• RFID is also called dedicated short range communication
(DSRC)
Components of RFID
An RFID tag is an object that can be attached or stuck to a product, animal, or person for the purpose of identification using radio waves.
TAGS(Chip +Antenna + Substrate)
Tag types:
Active
Passive
Semi Passive
Frequency at which these tags are used
*Between 125 and 134 KHz
*At 13.56 megahertz
*At 2.45 GHz
Electronic Product code-EPC
Each tag contains a unique code that facilitating the identification process & is known as EPC.
E.g. 613.23000.123456.123456789(96 bits)
Header –defines version of EPC (8-bits)
EPC manager –describes originator of EPC(product manufacturer) (28 bits)
Object class-could describe the product type (24 bits)
Serial Number-Unique ID for that product item (36 bits)
USING PROCESS OF RFID IN FEDEX
FedEx has been using RFID technology since 1999. FedEx Ground currently uses wireless RFID technology for asset tracking in a business to consumer (B2C) environment. RFID makes the leap from the old handheld scanners to the new Bluetooth Pocket PCs making FedEx the efficiency expert. Radio Frequency Identification (RFID) is an integrated technology allowing businesses to easily monitor the arrival and automatically retrieve data. For example, if a shipper wants to know where Customer A’s package is, the shipper just has to enter a reference number into the Pocket PC and it will directly tell you where the package is located in inventory. The use of RFID helps to reduce inventory overload in storage as well as the tracking and monitoring of shipments. “FedEx, using Bluetooth and GPRS, ensures efficient dissemination of information in which customers are able to clearly locate packages in shipment” (Emigh 2004). Tracking enables one to locate packages in a country, storage/inventory or in delivery. Hence, it is like a secret key to the transportation process. For instance, a customer sent a parcel to his friend in China, but would like to know where it is – this can be found using a RFID tag that will obtain information that the parcel is on the FedEx Ground truck crossing Country ‘X’.
