| Argument | Description |
| Identifier | AutoID Identifier according to the device configuration as returned as part of a ScanResult in a scan event or scan method. The ScanData DataType is defined in 9.4.2. If the ScanData is used as returned in the ScanResult, the structure may contain information that must be ignored by the AutoID Device. An example is the ScanDataEpc where only the parameter UId is relevant for this Method. If the Identifier is provided from a different source than the ScanResult, a ScanData with a ByteString can be used to pass a UId where the CodeType is set to ‘UId’. |
| CodeType | Defines the format of the ScanData in the Identifier as string. The String DataType CodeTypeDataType and the predefined format strings are defined in 9.1.3. |
| Region | Region of the memory area to be accessed. If there is no bank available this value is set to 0. This is the bank for UHF (ISO/IEC 18000-63) or the bank (ISO/IEC 18000-3 Mode 3) or data bank (ISO/IEC 18000-3 Mode 1) for HF. |
| Offset | Start address of the memory area [byte counting] |
| Data | Data to be written |
| Password | Password for write operation (if required) |
| Status | Returns the status of the write operation. The AutoIdOperationStatusEnumeration DataType is defined in 9.2.1. |
