The only remarkable thing about this coming from the perspective of Sweden would be if there is no ungated exit, for example at the manned checkout. Having one-way gates at the entrance has been standard practice for as long as I've been alive, and basically ever since self-checkout became a thing, they have been receipt-gated.
You've always been able to exit by the manned checkout though as for obvious reasons you can't imprison people who visit your store
Coldbox, but yeah
