Abstract: Methods and apparatus for wireless communication of time and attendance information are disclosed. A time and attendance device may include a receiving unit and a transmitting unit. The receiving unit may be configured to receive identification information that identifies at least one user of the time and attendance device. The transmitting unit may be configured to transmit the received identification information to an external server over the wireless network. Related time information that indicates a time at which the receiving unit received the identification information may be captured and also transmitted to the external server.

Abstract: A two-dimensional, high-density, damage-tolerant printed code suitable for encoding multiple biometrics and text for positive off-line identity verification comprises a horizontal header section; a vertical header section; a start pattern; a left row address pattern; an encoded data portion; a right two address pattern; and stop pattern. The horizontal header section encodes the number of bit areas in a transverse row of the encoded data portion; and the vertical header section encodes the vertical height of each bit area. The start and stop patterns of the code demarcate the lateral extent of the code (i.e., the beginning and end) from the adjacent quiet zone. Information is encoded into the ended information portion in bit areas that may be printed or blank. The information is encoded sequentially in the information portion from the top of the encoded information portion along each transverse row of bit areas to the next row of bit areas until the end of the encoded information portion.
