A communications system may include a plurality of electronic devices each configured to wirelessly communicate via an NFC format and another wireless communications format(s). A first electronic device may have an NFC transfer parameter associated therewith, and may be configured to establish an NFC link with a second electronic device of the plurality of electronic devices when in proximity therewith, designate data to be transferred to the second electronic device, and determine whether the designated data complies with the NFC transfer parameter. Based on a determination that the designated data complies with the NFC transfer parameter, the first electronic device may be configured to transfer at least some of the designated data via the NFC link, and otherwise transfer at least some of the designated data to the second electronic device over a separate wireless communications link using the at least one other wireless communications format.
