1. A system for communication, comprising:
a basic function module;
at least one extended function module;
a first near-field communication transceiver and a first near-field communication antenna, located on the basic function module, the first near-field communication antenna including a first loop antenna and a main printed circuit board; and
at least one second near-field communication transceiver and at least one second near-field communication antenna located an each respective at least one extended function module, each of the at least one second near-field communication antenna including a second loop antenna and a main printed circuit board;
wherein planes where the main printed circuit boards on the basic function module and the extended function modules are located are parallel to each other, a height difference between the planes where the main printed circuit boards on two adjacent modules are located is less than a threshold, and the threshold is based on a set near-field communication distance.
