Security experts say 2013 could be a bad year for your smart phone.
They predict that smart phones will be a major target for cyber criminals.
The main reason is that more smart phones are being used as "virtual wallets."
So, mobile payment systems are a tempting target for hackers.
Thieves can also use your smart phone to connect to other devices.
So what can you do?
The experts say don't get careless.
Make sure your phone is protected by a password.
And don't buy things over a public WiFi connection.
