UCA Extra iButton Programming Keys (Only For Programming)!

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 keychains. Innovative packaging protects the electronic circuits inside the canister from dirt, moisture, corrosion and static discharge.

Touching a Data Chip to the reader instantly transfers a 46 bit data stream of digital data which allows the user access to a secure 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. This ibutton is not to be used as as a "user key". It's only function is for programming the UCA locks.
