RFID is able to do what barcode is currently able to do, and more. Firstly, RFID system does not require line of sight to achieve the reading of information and is able to penetrate through most common materials such as paper and plastic. However, it may have limitation on reading through metal and liquid.
In addition, RFID allows serialization with allocation of unique serial number being assigned to every item. RFID also is superior compared to barcode system when it comes to speed and memory size. As such, RFID is able to read at a faster communication speed on the go and able to store data in the tag.
