Glossary Of Rfid Terms -- H
Harvesting
A term sometimes used to describe the way passive tags gather energy from an RFID reader antenna.
High-frequency
This is generally considered to be from 3 MHz to 30 MHz. HF RFID tags typically operate at 13.56 MHz. They can be read from less than 3 feet away and transmit data faster than low-frequency tags. But they consume more power than low-frequency tags.
Host system
A computer on a network, which provides services to users or other computers on that network.
Hybrid card
A smart card that has both a contactless IC and a contact IC. Unlike a dual interface card, a hybrid card acts as two separate cards.
Hysteresis
A retardation of an effect when the forces acting upon a body are changed. When corrugated boxes and other materials absorb water and then dry, they are never as RF-friendly as they were before they became moist.
