Barcode and RFID tags help companies track objects with ease. Both types of tag store data relating to the object which can then be easily scanned and accessed via an online platform or mobile scanner.
RFID allows multiple tags to be scanned at once which results in a faster reading. It will still allow you to identify each individual object however, and not duplicate the same item which can be a recurring issue with a barcode.
You don’t need line of sight for RFID tag reading. If you are within range and using the correct tag, you can read them even at a distance. Barcodes require the scanner to have a direct line-of-sight with the code.
RFID tags are sturdier, more reusable and can be read in harsher environments. Tags can be embedded within the object if necessary and advanced tags can even have sensors for temperature, humidity or moisture. Barcodes are typically printed on adhesive labels prone to damage which can impact the readability.
RFID tags can store more data and have a higher degree of complexity, like product maintenance information and expiry dates per individual item. Barcode tags can only store a limited amount of data, usually generic information like name, SKU, and manufacturer.
When choosing between barcodes or RFID, it is essential to look at the purpose, environment and potential costs. Not all cases require RFID tags to be used, but some other case will require the technology.
