Businesses and credit cards

I’m writing an article for, a credit card comparison and credit card news site, and I’m tackling the topic of identity theft and small business credit cards. I’m looking for credit card experts, business consultants and business owners. For the business owners: I’m wondering if you’ve ever had an employee had their business credit card stolen and do you have any policy on what an employee should do if they learn their credit card has been compromised? And how in general do you protect your credit cards and your consumers from identity theft? And for the credit card experts or consultants – I’m looking for advice for business owners on keeping their credit cards safe from identity thieves or for anecdotes, if you have any, of businesses that have had their credit cards compromised.
