Aaliyah company owns near-field communication for the retail stores.
A set of protocols known as near-field communication (NFC) enables two electronic devices to connect within a 4 cm range (112 in). Stronger wireless connections can be started via NFC, which offers a sluggish connection with a straightforward setup. With a frequency of 13.56 MHz in the widely accessible unlicensed ISM band and the ISO/IEC 18000-3 air interface standard, NFC is based on inductive coupling between two so-called antennas present on NFC-enabled devices, such as a smartphone and a printer, communicating in one or both directions at data rates ranging from 106 to 424 kbit/s. Other technologies that make use of "proximity cards" are similar to this one.
