| Glossary Term | Definition |
| IATA CODE | A modified version of the Standard 2 of 5 barcode used to sequentially number airline tickets. |
| IEEE802.11a | Standard protocol for a wireless local area network operating around the relatively interference-free 5 GHz frequency band. It has a raw data rate of 54 million bits per second and 8 non overlapping channels making it ideal for high density deployments. Properly configured it offers higher data security than IEEE802.11b. It is not interchangeable with IEEE802.11b. |
| IEEE802.11b | Standard protocol for a wireless local area network operating around the 2.4 GHz frequency band. It is the most cost effective of the 802.11 standards to implement and 'WiFi' product certification is a very good indication of manufacturer interoperability. It is the 802.11 variant most suitable for handheld computers because the client cards use less power and the access points cover a wider area. The maximum raw data rate is 11 million bits per second. |
| IEEE802.11g | Emerging standard protocol for a wireless local area network operating around the 2.4 GHz frequency, with a raw data rate of 54 million bits per second. It is backwards compatible with 802.11b WiFi devices. |
| IEEE802.11i | Backward compatible interim wireless networking standard designed to strengthen WEP key encryption and address other security issues exposed in earlier versions of the 802.11 standard. |
| IMAGER |
Imager technology uses a small camera to capture 1d and 2d barcodes. It then decodes the barcode using digital image processing. The area to read is usually illuminated by LEDs and the aiming mark is provided by a laser. |
| INK LAYER | The bottom layer of a thermal ribbon which is composed of wax, resins, or a combination of both. |
| INLAY | RFID hardware mounted on label material. Inlays provide the RFID portion of “smart labels”. See also Smart Label. |
| INTERCHARACTER SPACE | The space between two adjacent bar code characters. |
| INTERLEAVED 2 OF 5 | Interleaved 2 of 5 is a continuous, self-checking, numeric symbology employing two element size widths. Characters are paired together with each character composed of five elements, two wide and three narrow. Can be used to represent the characters 0 to 9. |
| INTER-LABEL GAP | The space, notch, or hole between labels used by the media sensor on the printer to determine the label length and top of form. |
| INTERLEAVED 2 OF 5 | Interleaved 2-of-5 is a linear symbology that is most often used for encoding large amounts of information in a small area. Characters are paired together using bars to represent the first character and spaces to represent the second. Interleaved 2-of-5 bar code applications are prevalent in the electronics and manufacturing areas. |
| INVENTORY CONTROL | Applications where bar coding and other forms of AIDC are used to add or delete items from inventory with 100% accuracy. |
| IP RATING | The Ingress Protection rating given to an electrical device is a two digit code indicating the level of protection it conforms too. The first digit represents protection against penetration by solid objects accessing hazardous parts, the second describing the enclosures, protection against the ingress of water. |
| IPS | Inches per second (refer to Print Speed). |
| IrDa | Infrared Data Association (1) A trade association. (2) A scanning technology that utilizes electromagnetic radiation wavelengths longer than those of visible light and shorter than those of microwaves. |
| ISBT 128 | An international standard for the bar code used on blood packaging enabling critical information such as blood type and expiry date to be accurately transferred between participating facilities. A derivation of Code 128, it is now registered for use in facilities in 28 countries across all five continents. |
| ISS SUPERCODE | SuperCode is a packet bar code symbology, a variant of a multi-row symbology. There are precise rules for the horizontal placement of symbol characters in a packet, but greater freedom in placing packets vertically and horizontally than offered by a matrix of columns and rows in a multi-row symbology. |
