Abstract
The present invention relates to RFID keypad assemblies and, more particularly, to embodiments of RFID keypad assemblies having two or more keys, such as keys that are depressible by a person'"'"'s finger, each key being associated with a RFID transmitter and capable of enabling the transmitter to transmit a signal that may be read by a compatible RFID reader. Activation of a key may, depending on the embodiment, either enable or disable transmission of any particular RFID transmitter with which it is associated. This provides a RFID keypad assembly that may be made and used as a wireless communication device. Examples of practical applications for a RFID keypad assembly include, but are not limited to: confirming an identity, controlling an object, and requesting a service. Embodiments of RFID keypad assemblies of the present invention may include any of a wide range of variations to enable their use for a diversity of practical consumer, commercial and industrial applications.
