An exemplary method of decoding a barcode uses a barcode template of known fixed fields in the barcode to enhance error correction in decoding of the barcode. A barcode having encoded data is scanned with an exemplary electronic device including a barcode scanner, a memory, and a barcode template stored in the memory. The barcode template includes fixed data fields and variable data fields. The barcode's encoded data are sampled into a codeword array, and a barcode template that matches the format of the scanned barcode is selected. Typically, error correction is then performed on the codeword array, and the error-corrected codeword array is then outputted.

Method of barcode templating for enhanced decoding performance

An encoded information reading (EIR) terminal can comprise a microprocessor, a memory, a communication interface, and an EIR device, all communicatively coupled to a system bus. The EIR device can be provided by a bar code reading device, an RFID reading device, and/or a card reading device. The EIR terminal can be configured, responsive to reading an encoded message by the EIR device, to produce a decoded message string by decoding the encoded message. The EIR terminal can be further configured to produce an output string by formatting the decoded message string according to one or more formatting commands. The formatting can comprise excluding from the output string a symbol of a specified encoding type according to a Discard Data formatting command.

Encoded information reading terminal with data formatting functionality

There is provided for herein a terminal having a radio transceiver, the radio transceiver having a maximum output power and an operating power. The operating power is limitable to a power limit that less than or equal to the maximum output power and is operator selectable from a set of power limit values so as to reduce interference with other devices operating in the 2.4 GHz spectrum of the ISM band. In one embodiment, the set of power limit values includes the maximum output power and a plurality of additional values. In another embodiment, the set of power limit values includes a plurality of values, the plurality of values including at least first and second values less than 16 dB apart in magnitude.
