Digital Forensics in Small Devices: RFID Tag Investigation

2.1.1 RFID Transponders or Tags
The transponders or tags are small items similar to the small portions of paper
with a metal printed pattern, as shown in Figure 2.3 below (Xiao et al., 2007).

Even though the tags come in different types (Figure 2.3), different shapes and
different classes; their main functions are not only to store the unique information
of an object or a person, but also to respond to the request for information coming
from the RFID reader (Hunt et al., 2007; Sanghera et al., 2007).

A tag is basically made up of an electronic chip, antenna and substrate (see
