An RFID device may include one or more manually activated RFID tags configured to transmit unique RFID signals in response to a manual activation thereof. A transaction may be defined upon receiving a confluence of multiple RFID signals at the same time, or at nearly the same time, at an RFID reader. A transaction may also be defined upon receiving multiple RFID signals or confluences of such signals in a predetermined series or sequence. The RFID devices may include a single manually activated RFID tag, or two or more of such tags, which may be individually activated by one or more manual interactions from a user.
