käynteinä

Käynteinä refers to an authentication system used by Finnish public swimming pools and many other aquatic facilities. It involves the use of personal identification codes, which can be obtained from the facility's website, online service, or directly from the customer service of the facility.

Users register for a personal account with their preferred facility. After registration, a unique identifier is generated and sent to the user. This identifier must be entered or presented at the entrance of the facility to gain access. The identifier does not contain a photograph, making it a faceless card system.

The system allows for quick and easy registration before any visit to the pool, as well as efficient management for pool staff. This method of getting into the pool with the help of an ID number is helpful for frequently visited users who quickly need access.

It is intended to improve customer experience and help management of the facility to manage entry more efficiently.
