Glasgow-based Swipii has secured funding of £1 million into its cashback app. The investment has been made by Scottish private equity company Par Equity, which is an existing investor in the business. Swipii aims to be the simplest way for consumers to earn cashback as they shop. Once someone has securely linked their bank payment card to the app, they automatically earn cashback every time they pay with that card in a participating retailer. There is no need to scan codes or carry multiple reward cards.
