Abstract: Near-Field UHF wireless coupling may be used to write data into a non-volatile memory in a device, thus allowing for changes to be made to the device after that product has been manufactured. Energy from the received wireless signal may be used to power sufficient circuitry in the device so that the programming does not require an on-board power source such as a battery. In many cases, the device may be programmed after it has been packaged for shipment/sale, without removing the device from the package. In some embodiments, a multi-segment antenna may be used to program multiple such devices at the same time by the same Near-Field UHF signal.
