The Role of RFID in a more Transparent Textile and Apparel Supply Chain
By Belinda Carp
What is RFID? RFID stands for Radio Frequency Identification and it is a method used for tracking goods via wireless signals, in order to transfer data between microchips. The chips are typically inserted into tags or cards which contain electronically-stored information and transmit a radio signal. What is the role of RFID in the textile supply chain? In the textile and clothing supply chain, RFID helps companies to improve item-level accuracy and improve the efficiency of the global retail supply chain and the transparency of the textile supply chain. The visibility gained by RFID results in a reduction in waste and therefore lower consumption of natural resources, and is therefore increasingly important as textile companies employ technology and incorporate changes to improve their environmental and social responsibility across the supply chain. How does it work? An RFID system comprises three main components, namely:- RFID tags;
- an RFID reader; and
- an RFID inventory management computer software.
RFID tags
Electronic tags are attached to items of stock. Each tag is digitally coded with information about the item’s characteristics, such as its size, color, price, age and/or date, and country of manufacture.
The tag helps to improve the traceability of an individual item, and is often provided with the labeling solutions, in a hang tag, or care label. Labels which contain QR codes can be scanned by consumers who wish to learn more about the supply chain that produced their goods.
Tags can also be attached to a batch of items. Such tags contain information about all the items in the batch, including the total number of items contained within the batch.
There are two types of RFID tags: active and passive.
Active RFID tags have a battery which supplies the power for communication. They send out alerts which inform the reader of their location and are therefore useful for tracking goods.
Passive RFID tags do not have a battery and therefore cost less. Instead, the RFID reader provides them with the energy needed to send and receive signals.
RFID Reader
The information in the tags is picked up on an RFID reader via radio waves. The reader gathers data from the tags by transmitting and receiving radio frequency signals to and from the electronic tags.
The data collected on the RFID reader are then accumulated and presented to the user via RFID inventory management computer software.
There are two types of RFID readers: portable and non-portable.
Portable readers include handheld devices, which are mostly used for counting purposes.
Non-portable readers include so-called walkthrough gates which are installed at the entrances and exits of the warehouse and which detect the items and store their data in the digital database as soon as the items pass through the gate. The walkthrough gates act as security guards and immediately alert the warehouse staff if someone tries to steal a product from the warehouse,
RFID Inventory Management Computer Software
The RFID inventory management computer software creates a central database of information, and enables users to refresh, update, read, analyze, and react to data which have been gathered.
The database stores information about various items present in the warehouse inventory, such as their time of arrival and manufacturer details.
Having an efficient inventory management system in place can help a company to cut costs and automate its inventory management processes.
Who Needs RFID?
RFID technology is regarded as key to getting 100% reliability relating to the location of a shipped item at any given time, and the time at which it reached its destination. The information is valuable to the logistics company and to apparel manufacturing companies which rely heavily on logistics.
Examples of sectors in the textile and apparel supply chain which benefit from RFID technology are:
- companies offering industrial laundering services, such as those which clean uniforms and/or hospital garments and linens;
- companies offering clothing distribution services;
- wholesalers; and
- retailers
