The Phone as a Key

01 · BACKGROUND

The Problem

The gym is open around the clock but staffed only during the day. Members who forgot their key fob in the evening or on weekends found themselves locked out. Lost fobs had to be replaced and deactivated in the system, which cost money and administrative time.

02 · SOLUTION

How SMS Solves the Problem

The access system is connected via the SMS API. When a member enters their mobile number at the door terminal, the system verifies their membership and sends a personal daily code by SMS within seconds. This code opens the door, and the key fob is now just an option.

The Benefits

BENEFIT 01

No Key Fob Needed

Almost everyone has their phone with them at all times. A forgotten or lost key fob is no longer a reason to drive back home.
BENEFIT 02

24/7 Access

Members work out early in the morning, late at night, and on weekends. No one has to staff the front desk for that.
BENEFIT 03

Full Control

Each code is valid for one day only and then expires automatically. Members who have canceled or been blocked simply no longer receive a new code.
