A source WCD from among the plurality of WCDs may be configured to designate message data for at least one target WCD from among the plurality of WCDs, where the message data has a security restriction associated therewith. At least one intermediary WCD from among the plurality of WCDs may be configured to wirelessly receive the message data from the source WCD when in proximity thereto, and with restricted access to the message data based upon the security restriction. The at least one target WCD may be configured to wirelessly receive the message data from the at least one intermediary WCD when in proximity thereto and with less access restriction to the message data than the at least one intermediary WCD. ## Claims ### Claim at position 1 1-20. (canceled) ### Claim 21 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. ### Claim 22 (depends on 21) The wireless communications device of claim 21 wherein said at least one wireless transceiver comprises a near-field communication (NFC) transceiver. ### Claim 23 (depends on 21) The wireless communications device of claim 21 wherein said controller is further configured to prohibit delivery of message data to the target WCD outside of an associated delivery time period. ### Claim 24 (depends on 21) The wireless communications device of claim 21 wherein said controller is further configured to prohibit delivery of message data to the target WCD outside of a geographic delivery area. ### Claim 25 (depends on 21) The wireless communications device of claim 21 wherein said controller is configured to pass an acknowledgement from the target WCD to the source WCD. ### Claim 26 (depends on 21) The wireless communications device of claim 21 wherein said controller is configured to generate at least one reminder to deliver the message data to the target WCD. ### Claim 27 (depends on 21) The wireless communications device of claim 21 wherein said controller is configured to notify the source WCD if the message data is not delivered to the target WCD within an associated delivery time period. ### Claim 28 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. ### Claim 29 (depends on 28) The wireless communications device of claim 28 wherein said controller is further configured to prohibit delivery of message data to the target WCD outside of a geographic delivery area. ### Claim 30 (depends on 28) The wireless communications device of claim 28 wherein said controller is configured to pass an acknowledgement from the target WCD to the source WCD. ### Claim 31 (depends on 28) The wireless communications device of claim 28 wherein said controller is configured to generate at least one reminder to deliver the message data to the target WCD. ### Claim 32 (depends on 28) The wireless communications device of claim 28 wherein said controller is configured to notify the source WCD if the message data is not delivered to the target WCD within the associated delivery time period. ### Claim 33 A method for wireless communications between a source wireless communications device (WCD) and a target WCD comprising: operating an intermediary WCD comprising at least one wireless transceiver and a controller cooperating therewith to 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. ### Claim 34 (depends on 33) The method of claim 33 wherein the at least one wireless transceiver comprises a near-field communication (NFC) transceiver. ### Claim 35 (depends on 33) The method of claim 33 further comprising operating the intermediary WCD to prohibit delivery of message data to the target WCD outside of an associated delivery time period. ### Claim 36 (depends on 33) The method of claim 33 further comprising operating the intermediary WCD to prohibit delivery of message data to the target WCD outside of a geographic delivery area. ### Claim 37 (depends on 33) The method of claim 33 further comprising operating the intermediary WCD to pass an acknowledgement from the target WCD to the source WCD. ### Claim 38 (depends on 33) The method of claim 33 further comprising operating the intermediary WCD to generate at least one reminder to deliver the message data to the target WCD. ### Claim 39 (depends on 33) The method of claim 33 further comprising operating the intermediary WCD to notify the source WCD if the message data is not delivered to the target WCD within an associated delivery time period.
