ABSTRACT:
A method and systems for collecting data from a huge number of pre-filled forms are disclosed. According to the method and systems of the invention, the pre-filled forms comprise RFID tags, check boxes, and electrical connection between the RFID tags and the check boxes so that responses are modified according to checked boxes. In a preferred embodiment, each check box comprises at least two electrical terminals electrically connected to the RFID tag through a register. Using a pencil with conductive ink for checking the check boxes establishes an electrical contact between the terminals that modify the value of the register that in turn, modifies the response of the RFID tag. When the check boxes identifiers of a form have been collected, the identifier of the form is stored within the RFID reader to avoid further reading of the RFID tag, or the identifier of the RFID tag is erased.
