Coop and Swisscard have mutually decided to end their distribution partnership for SUPERCARDplus as of October 31, 2020. Swisscard will no longer be issuing any new SUPERCARDplus cards from November 1, 2018. Existing customers can still use their SUPERCARDplus card until the expiry date, until October 31, 2020 at the latest though.
Even if you activate and use the Cashback credit card, you can still collect superpoints by showing your Supercard membership number (e.g. with the blue Supercard or by showing the digitalized barcode) with purchases at Coop and its partner businesses (e.g. Interdiscount, Fust, Livique). And this is in addition to cashback.
