In embodiments of hardware verification with RFID-stored build information, a mobile device includes hardware components and a radio-frequency identification (RFID) tag to store build information for hardware verification of the hardware components in the mobile device. A bootloader can interrogate the RFID tag to obtain the build information and compare the build information to current information of the hardware components in the mobile device. The bootloader can then determine whether the current information matches the build information. If the current information does not match the build information, then a message can be displayed on the mobile device indicating that unauthorized hardware is installed in the mobile device.
