Stop gym card misuse: Secure check-in via facial recognition
Membership cards, RFID transponders, and QR codes allow for quick check-in. However, they can easily be shared with friends or family members. The access system recognizes a valid credential, but not necessarily the authorized person.
For gyms , card misuse can lead to lost revenue, inaccurate visitor numbers, and additional administrative burdens. Manual verification is nearly impossible, especially during unstaffed hours and in 24/7 facilities.
Sharing cards costs you potential membership fees
The extent of the financial impact depends on your membership fees and the number of unauthorized users.
A simple calculation:
10 unauthorized users × 40 euros monthly fee × 12 months = 4,800 euros in potential annual revenue
In addition, there are the costs associated with manual checks, blocking cards, and managing suspicious check-in activity.
This issue is becoming increasingly important: in 2024, approximately 11.71 million people were members of a German fitness or health club. This represents a growth of 3.6 percent compared to the previous year.
Personalized check-in with the ID INFO 9000
iDTRONIC's ID INFO 9000 enhances access control with AI-powered facial recognition. This verifies not only the validity of a card but also the identity of the person at the entrance.
The terminal combines multiple identification methods:
• AI-powered facial recognition
• RFID cards and RFID transponders
• QR codes
• fully contactless check-in
• integration with turnstiles and doors
Check-in takes less than a second. Once identity is verified and membership is confirmed as valid, access is granted automatically.
Facetronic describes the combination of media usage and facial recognition as a way to detect and track access attempts made with unauthorized credentials.
Less card misuse, less administrative effort
Facial recognition makes the check-in process personal. This prevents memberships from being easily shared via passed-on cards or forwarded QR codes.
The benefits:
• fewer unauthorized entries,
• better protection of membership revenue,
• automated identity and authorization verification,
• fewer manual checks,
• reduced workload for studio staff,
• reliable operation outside of staffed hours,
• more precise check-in and occupancy data.
The team gains more time for consulting, sales, and member support. At the same time, the entrance area remains controlled in the evenings, on weekends, and during 24/7 operations.
Integration with existing studio systems
The ID INFO 9000 can be connected to established member administration and studio management systems, including:
• Magicline
• Centercom
• Virtuagym
• Agilea
The specific integration is reviewed on a project-by-project basis. In combination with a turnstile, this creates an automated process:
1. The member is identified.
2. The current membership status is verified.
3. If the authorization is valid, the turnstile is released.
4. The check-in is recorded in the system.
Virtuagym confirms that, in principle, hardware integrations for access control can automate administrative processes and reduce manual work.
Consider data protection from the start
Facial recognition involves the processing of biometric data. For the purpose of unique identification, this data is classified as sensitive personal data under Article 9 of the GDPR. EUR-Lex – General Data Protection Regulation
Before implementation, you should therefore review factors such as the legal basis, member information, consent, retention periods, deletion policies, and alternative check-in options. The specific implementation should be coordinated with your data protection officer or qualified legal counsel.
iDTRONIC supports you with the implementation
iDTRONIC supports you in planning a complete access solution consisting of:
• ID INFO 9000,
• RFID media,
• turnstile or door control,
This ensures you don't just get an isolated facial recognition reader, but a check-in process tailored to your gym.
Conclusion
The ID INFO 9000 makes check-in personal, fast, and contactless. AI-powered facial recognition makes it difficult to share memberships, protects potential revenue, and takes the pressure off your team.
