RFID (Radio-Frequency Identification) tags for Wood Identification

The barcode consists of a machine-readable code in the form of numbers and a pattern of parallel lines of varying widths, which is printed on an item or product.

This is a high reliability and accuracy method (Mousavi et.al. 2005). The RFID tag is extremely small and can be affixed to an object and used to track and manage inventory, assets, wood, etc. (Várallyai, 2013). Radio Frequency Identity (RFID) tags can be planted inside a wood log and transmit data to receivers. These RFID tags can be read-only or read-write, and can be programmed in the field or in advance. They are passive; they only transmit data when become ‘excited’ by a signal from the RFID reader. These tags are very durable, they can live up to 8 years, they can be reprogrammed and they can be read under water. Aiming to automatic identification and tracking, radio-frequency identification (RFID) uses a wireless non-contact system with radio-frequency electromagnetic fields for data transmission from a tag, in a product (Mousavi et.al. 2005). There is comprehensively literature about RFID technology reviewed in recent research (Várallyai, 2013), where it is studied the use of RFID aiming to improve supply chain and inventory operations. RFIDs are simple to hide or fit in other items due to its small size. The RFID technology is the most promising method for marking logs at this moment, as, unlike barcodes technology, RFID allows acquiring information at a rate of 1000 tags per second and it is expected a growing acceptance of RFID technologies in the next years as basic components within traceability information systems (Bechini et.al., 2008). The readability in the real-life tests and demonstrations was close to 100%. Apart from the technical performance RFID represents a sophisticated technology that opens up for new business applications. A further advantage compared to other methods is that it is not easy to deceive (Dykstra et.al. 2003). Still there is a need for further development of this technology. The automatic application must be very tough with a minimum of production disturbances. The current trend is positive for the RFID technology and generally the cost per tag is expected to decrease (FSANZ, 2012). Traceability in wood packaging material can be secured with the suitable thermal handling, as the technology of radio gives today adequate solutions. Apart from the simple thermal handling in wooden packaging material, other information can be stored on the same label such as quantity and origin of wood (Ntalos et.al. 2010). The cost of the method is now high but it still decreases.
