Wireless communications system providing wireless message data delivery through intermediary wireless communications device and related methods

A wireless communications device (WCD) comprising:

• at least one wireless transceiver;
• and
• a controller cooperating with said at least one wireless transceiver and operable between a source WCD and a target WCD by at least
• wirelessly receiving message data from the source WCD when in proximity thereto and with restricted access to the message data based upon a security restriction associated therewith, and
• wirelessly transmit the message data to the target WCD when in proximity thereto so that the target WCD has access to the message data without the security restriction.

A wireless communications device (WCD) comprising:

• at least one near-field communication (NFC) transceiver;
• and
• a controller and a memory coupled thereto, said controller configured to cooperate with said at least one NFC transceiver and operable between a source WCD and a target WCD by at least
• wirelessly receiving message data from the source WCD when in proximity thereto and with restricted access to the message data based upon a security restriction associated therewith,
• wirelessly transmit the message data to the target WCD when in proximity thereto so that the target WCD has access to the message data without the security restriction, and
• prohibit delivery of message data to the target WCD outside of an associated delivery time period.
