The HS-1RS integrates 1D and 2D barcode scanning with LF/HF RFID smartcard/contact-less and prox card reading functionality in a single, ergonomic, and compact design.

Traditional 1D bar codes (with printed bars and spaces) are giving way to 2D bar codes that also include dots, hexagons, and even colors to encode more data. Bar-code scanners read 1D bar codes.
