Use your body to prevent the person behind you from seeing your debit/credit card pin at the point of using the ATM.
Regularly check your statement of account to confirm if there are any records of strange or suspicious activities.
Change your password if in doubt that it has been compromised.
Give a strong password to your WiFi and make sure it is changed from time to time. Also, switch off the wireless device when not in use.

Personal information can be retrieved from trash cans if not well disposed of. Always ensure disposed paper works or documents are well shredded.
