Data transmission apparatus having a fingerprint reader and method thereof

A method of transmitting control data for controlling an electrical device, the method comprising:

• acquiring a fingerprint feature of a user's finger;
• selecting control data from a storage unit in accordance with the acquired fingerprint feature, wherein said storage unit stores at least a first and a second fingerprint features per one user and transmission data for at least a first and a second commands associated with said first and second fingerprint features, respectively, said first and second commands being different from each other;
• and
• transmitting the control data read out from said storage unit to an electrical device.

A remote controller for controlling an electrical device, comprising:

• a storage unit for storing a first control data and a second control data, wherein the first control data for controlling a first electrical device corresponds to a first fingerprint feature of a user's first finger and the second control data for controlling a second electrical device corresponds to a second fingerprint feature of a user's second finger;
• a fingerprint reader coupled to said storage unit, for acquiring one of the first and second fingerprint features, whereby reading out the first control data when the first fingerprint feature is acquired, and the second control data when the second fingerprint feature is acquired;
• and
• a transmitter coupled to said fingerprint reader, for transmitting the first control data when the first fingerprint feature is acquired by said fingerprint reader, and transmitting the second control data when the second fingerprint feature is acquired by said fingerprint reader.

A remote controller, comprising:

• a storage unit having a first table and a second table, wherein the first table stores first control data for controlling a first electrical device, wherein the first control data is associated with a first fingerprint feature of a user's first finger, and the second table stores a second control signal for controlling a second electrical device, wherein the second control data is associated with a second fingerprint feature of the user's second finger;
• a first table selector for selecting one of the first and second tables;
• a fingerprint reader coupled to said storage unit and said first table selector, for acquiring one of the first and second fingerprint feature, whereby reading out the first control data from the first table of said storage unit when the first table is selected by said first table selector and the first fingerprint feature is acquired, and reading out the second control data from the second table of said storage unit when the second table is selected by said first table selector and the second fingerprint feature is acquired;
• and
• a transmitter for transmitting one of the first control data and the second control data, which is read out from one of the tables of said storage unit by said fingerprint reader.
