McDonald's Sweden has added QR code payments to its mobile app with the integration of the SEQR mobile wallet from Stockholm, Sweden-based Seamless.

The existing McDonald's app already delivers menus with nutrition and allergy information as well as offers and campaigns, Kajsa Dahlberg, McDonald's Sweden's head of digital engagement, said in a statement. "Now our Swedish customers can also make payments through the app," she said.

Customers can make purchases at McDonald's restaurants across Sweden by scanning QR codes at the checkout and confirming payment by entering their PIN. The payment receipt is stored in the customer's phone.

McDonald's also plans to roll out SEQR-based mobile payments at its Belgian restaurants in the spring of 2014.

SEQR said that, by using its own transaction switch and bypassing the card companies, it is able to halve merchants' transaction costs.

Since its launch in 2012, SEQR has been adopted by 4,600 merchants, and the SEQR wallet is now available in Sweden, Norway, Finland, Kuwait, Malaysia and Romania. EMAB, owned by a coalition of independent Swedish merchants, has announced that it will accept SEQR payments at its 430 member stores in April 2014.

According to Seamless, SEQR is the only mobile payment solution on the Swedish market that allows consumers to pay in stores and online. In addition to making payments, users can carry out P2P transfers, save receipts digitally, connect loyalty programs, pay for parking and redeem offers through digital coupons.
