A retail terminal assembly includes a portable communication device for use by retail personnel. The assembly also includes a signal transmitter for transmitting a personnel-request signal to the portable communication device. The assembly further includes a processing unit electrically coupled to the signal transmitter. Moreover, the assembly includes a memory device electrically coupled to the processing unit. The memory device has stored therein a plurality of instructions which, when executed by the processing unit, causes the processing unit to (a) detect an intervention-needed activity and generate an intervention-needed control signal in response thereto, and (b) operate the signal transmitter so as to transmit the personnel-request signal in response to generation of the intervention-needed control signal. A message is communicated to the retail personnel by the portable communication device in response to receipt of the personnel-request signal by the portable communication device. A method of operating a retail terminal is also disclosed.
