# key.fit > key.fit is software for fitness studios: studio management and access control in one product. Members, contracts, SEPA direct debit and doors run in one application; whoever has paid can train - automatically, at every location, during opening hours. Operated by Aberger Software GmbH, Austria. The user interface is German. ## Access follows the contract - An active contract opens the door; an ended or locked contract does not. The membership status decides, with no list to maintain and no staff on site. - The chip opens the door even while the studio's internet connection is down. - Every entry is logged; who was at which door and when can be looked up at any time. - Entry only during opening hours, configurable per location. ## Billing and SEPA - Monthly fees are collected by SEPA direct debit from the same application, with no add-on module. - One debit run per month with an export file for online banking. - Returned debits (camt.053) are imported; every member who has not paid is listed with the reason. - Open items and account settlement per member. ## Members and contracts - The studio defines its own contract types with term, notice period and extension. - Starter package, contract change for an existing member, cancellation and online withdrawal are handled in the application. - Member sheet with master data, photo, chip, contract, account and door log on one page. - A confirmation mail goes to the member after every contract change. ## Several studios, one chip - One member, one chip, all locations of an operator - or selectively only one. - Opening hours, doors and permissions are kept per location; member management stays one. ## Self-registration at the entrance - Scan the QR code at the entrance, enter the data on one's own phone, take a photo, confirm the contract and the SEPA mandate. - The studio reviews the registration and approves it. ## Door technology - The firmware of the locking system and the door technology is key.fit's own. - The hardware is standard hardware; a studio may also order it from a mail-order supplier and have its own electrician install it. ## Operation, language, data - Operation and maintenance by Aberger Software GmbH, Austria.
