Radio Frequency Identification


For labs, the standard example of RFID deployment is its high-throughput application that has been shown to reduce freezer sample inventorying times by up to 7200% compared to traditional barcoding. Today, RFID is increasingly being used to give lab businesses a comprehensive, real-time “bird’s-eye view” of manufacturing, testing, and other processes -without staff ever touching a key or a mouse.

Unique UHF RFID characteristics:
– No line of sight –
– Read a population of tags simultaneously and quickly –
– Tags are relatively inexpensive –
– Tags come in a wide assortment of sizes and form factors –
– Longer ranges past +30 feet as well as very short ranges in inches –
– Data on the tags can just be an ID or hold higher data content –

Is RFID better than barcodes?

RFID tags and barcodes both contain information for identification and tracking. Barcode readers require a direct line of sight to scan the barcode whereas RFID readers only need the tagged item to be within a specified proximity. Many times, an RFID reader can identify tagged items at distances over 200 feet away. The typical range for a barcode reader is usually around 15 ft.

Another advantage of RFID over barcoding is the functionality of RFID tags in adverse environments. The presence of frost, ice accumulation, or suspension in liquid can prevent barcode scanners from reading barcoded items. Because RFID uses radio frequencies, it is less susceptible to these effects and items are quickly located and tags are able to function fully in many types of acid, liquid nitrogen, and other environments.
