I use credit cards for both my business and personal life. I rarely run a balance, preferring instead to pay in full each month. We purchase about $400,000 worth of merchandise to sell on eBay and Amazon a year and we earn travel points on that which we use to pay for airfare & hotel to attend trade shows.
In the past year, I have had one instance of someone getting my CC info and making trips overseas that I didn’t get to go on. Fortunately, I caught it quickly and Bank of America Visa cancelled the charges and the card and sent me a new one.
But I have also had three separate instances of seeing small charges on my card that I did not recognize. All of the charges were under $5.00 a month, so they are easy to miss. All three of these were on my American Express card. So, I disputed the charge and since the vendor had no proof that I bought a product or service, American Express charged them back to the vendor and credited my account. In one case, they were not able to contact the company at all, so the blocked that company from accepting American Express.
I am now in the habit of checking mt CC statements online at least weekly, and when I receive a statement in the mail, I review it line by line. The other thing you want to look out for are one-time hidden charges by your CC Company.
Lastly, if you have been good at paying your charges on time, call (use telephone –not email) your Credit Card Company at least yearly and ask if you qualify for a lower rate. Every time I have done this, they lowered my rate by at least 1.5%.
