Corby Data Chips contain sophisticated electronics to store a personal identification number in a coin shaped, sealed, stainless steel canister. This superior design allows the Data Chip to be easily attached to any smooth surface including existing photo ID cards, badges, or key chains. Innovative packaging protects the electronic circuits inside the canister from dirt, moisture, corrosion and static discharge. A Data Chip Adapter is required for each reader. Touching a Data Chip to the reader instantly transfers a 46 bit stream of digital data that allows the user access to a secured area. Unlike keys or other security cards, the Data Chip is user forgiving. It doesn't need to be precisely aligned to transfer its digital data.
