This paper describes a case study to identify the various parameters that affect the scanning reliability of 2D barcodes for high content density applications. A review of the numerous options for 2D symbologies showed that, in theory, these symbologies are capable of encoding relatively large amounts of data, but in practice, barcode scan-ability decreases as the encoded content increases.

Radio frequency identification (RFID) is a new generation of automatic identification systems, based on wireless communication technology. In these systems all the tags using one communication channel to communicate with the reader.
