still required. This option is more of a ??????semiautomated??™??™ receiving process. The handheld
reader is a mobile reader carried by an employee as illustrated in Figure 16.3. It is
composed of a rugged exterior and contains a keyboard and a terminal. It offers the
advantages of portability in remote locations. For example, if receiving is performed in a
temporary location or one that is not accessible by an RFID mounted forklift, then the
handheld reader is an interesting alternative. Unfortunately, its portability has to be offset
by a reduced Effective Radiated Power (ERP) in order to reduce the consumption of the
limited battery power supply. Rather than be considered as an alternative to RFID portals
and RFID mounted forklift readers, the handheld reader can also complement the other
equipment options for exception processing.
