Environment description
The Square Contactless and Chip Reader (“Reader”) is a secure payment device that is
designed for use by merchants in many industries for accepting card-present payment
transactions. The Reader only works with the Square Register application and a compatible
mobile device
running in a Square Stand (https://squareup.com/stand). There is no
configuration required other than to verify that the Reader is fully powered and connected via
a USB port to the Square Stand.
Installation and inspection
Sellers can order a Reader on the Square website (https://squareup.com) or purchase one at a
number of retail outlets (https://squareup.com/retail). Upon receipt of the Reader, the Seller
should inspect that the hardware version (S8) and serial number are visible on the underside
of the Reader.
