Chipped versus chipless RF identification: a comprehensive review

RF identification (RFID) is a well-known wireless technology that has emerged for capturing data from a stationary or dynamic object. This is one of the key technologies poised to replace barcodes, which are low in data capacity and difficult to reprogram. To address this storage-of-data limitation, the silicon RFID chip was developed. Auto ID-based technologies such as optical barcodes and RFID address the function of "contactless" behavior, which eliminates the impracticalities of mechanical touch and enables the performance of defined tasks.
