How is fraud prevented from being performed by this device?

Can anyone sign up for an account? Can anyone, say a waitress, scan my card information into their phone while taking my card to their business' cash register? What kind of information is stored on the devices taking the information?

    There was a brief security issue earlier in the year related to information that was retained on the device, but a later software update fixed the issue. There should be no personally identifiable information on the device after the transaction is complete.

    Also, Square monitors accounts for fraudulent activity. There is always a risk of credit card fraud from bad actors, but you may call your issuing bank if you have any questions or concerns related to activity on your account.
