Abstract
Devices and methods for protecting a radio frequency identification (RFID) device from electronic reading prior to the sale of the RFID device where a package includes an upper layer comprising a radio frequency shielding material covering at least the upper and side portions of an RFID device. The package also includes a lower layer covering the lower portion of the RFID device, where the lower layer is connected to the upper layer. The package also includes a tamper indicator that provides a physical indication of when the package has been at least partially opened or damaged. The package may be composed of plastic sheeting incorporated with radio frequency shielding material, such as a ferrous material, and in some embodiments may include a plastic film envelope incorporated with radio frequency shielding material encasing the RFID device.
