Discussed herein are techniques and implementations for deployment of machine-readable indicia on objects. The deployment can be achieved with a mechanical device to affix the machine-readable indicia to an object. The machine-readable indicia can be applied to the mechanical device, which then can be affixed to the object. The mechanical device can be portable and easily affixed to the object with snap-coupling fasteners. Structures on the mechanical device can help to locate and/or maintain the device on the object.
