Polish ecommerce marketplace Allegro and PKO Bank Polski have deepened their embedded-finance partnership, allowing users to open a PKO Konto za Zero bank account and activate Allegro Klik directly within the shopping app. Allegro Klik has attracted more than 370,000 users and offers one-click payments plus cashback of up to PLN1,200 annually. The partners said the integration removes the need to leave Allegro when accessing banking services. (Allegro)
