Abstract
Methods and systems are provided for evaluating shopping cart wheels using a sensor module or one or more microphones engaged with the shopping cart. The microphones can be used to detect sounds generated by the wheels of the shopping cart. A sound signature can be determined from the detected sound and compared to sound signatures in a database. If the detected sound indicates that a wheel of the shopping cart is failing, an alert can be generated using an associate alert system.
