National Measurement Institute Certified Sticker
Square has produced a sticker indicating the scale connection to our Point of Sale has been certified by the National Measurement Institute (NMI). When you purchase a USB scale or the cables through Square Shop, you will be supplied a sticker with the NMI certification number.
You must clearly place this sticker on the device running the Square Point of Sale app (i.e. Square Stand, Android tablet/smartphone or Square Terminal). The sticker helps NMI field inspectors identify that Square has fulfilled all compliance regulations for the certification from the NMI. Contact Square Support if you need a complimentary replacement sticker.
Important to note: To be compliant for the certification, you need to connect a physical printer if you’re using a scale with Square Stand, Square Register or Android device.
