Precautions while using ATM Machines
Review your bank account statements promptly
Review your bank account statements promptlyand report any errors including transactions you believe may be unauthorized as soon as possible. Again, a prompt notice will limit your potential liability for unauthorized transactions. If you insert your card in the ATM of another bank and it says invalid activity , try the ATM of your own bank. There might be a technical problem. However if this message keeps coming, request your bank for a new ATM card.
