| Glossary Term | Definition |
| HALF DUPLEX | A term used in data communication to indicate that data can not be simultaneously transmitted and received from a device. It must transmitted first, then clear the line and wait to receive data. With full duplex there are separate communications for transmitted data and received data. The amount of data that can be sent is therefore increased. |
| H.323 | An umbrella standard from the International Telecommunications Union (ITU) that addresses call control, multimedia management, and bandwidth management for point-to-point and multi-point conferences, as well as interfaces between LANs and other networks. The most popular standard currently in use. |
| HANDHELD PC (HPC) | The term adopted by Microsoft and its supporters to describe handheld computers employing Microsoft's Windows CE operating system. |
| HANDHELD SCANNER | A hand-held scanning device used as a contact bar code reader or OCR (optical code) reader. |
| HEAT RESISTANCE | The property of a material which inhibits the occurrence of physical or chemical changes caused by exposure to high temperatures. |
| HELIUM NEON LASER | A type of laser commonly used in bar code scanners that emits coherent red light at a wavelength of 633 nm. |
| HE-NE | A common name for a helium neon laser. |
| HIBC | Health Industry Bar Code. |
| HIBCC | Health Industry Business Communications Council – a trade association responsible for the symbology and label format used by the healthcare industry. |
| HI CO | High Coercivity. See coercivity. |
| HIGH DENSITY | This bar code type has narrow spaces and bars with an “X” dimension that is less than 7.5 mils. |
| HIGH FREQUENCY TAGS | RFID systems that operate at 13.56 MHz with a typical maximum read range of up to 3 feet (1 meter). |
| HOLDING POWER | The ability to withstand stress, as in holding rigid label materials on smaller diameter cylindrical objects or in holding weight. |
| HORIZONTAL BAR CODE | A bar code or symbol presented in such a manner that its overall length dimension is parallel to the horizon. The bars are presented in an array that looks like a picket fence. |
| HUE CODE | Developed by Robot Design Associates, this proprietary code is made up of blocks of cells coded using shades of gray or colour. Using dye sublimation printers over 40,000 bytes of data can be encoded per square inch. Intended to store text information on the back of business cards or medical cards it is read using a flatbed image scanner and proprietary software. |
| HUMAN READABLE INTERPRETATION | The interpretation of bar code data, often printed immediately below the bar code in a readable format to humans. |
