Anyone can receive an offer for a small business credit card—whether they own a small business or not. But consumers might want to think twice before they take the lender up on the offer.

Some of the key points of the study were:

80 percent of business cards Pew studied included an "any time" change-in-terms clause with no right to opt out, which means bank issuers can change account terms at any time with little or no notice.

Terms cannot change for the first year for consumer cards, and 45 days' notice is required when terms are changed, and consumers generally may opt out.

84 percent of business cards gave issuers the sole power to apply payments to low-rate balances first, which maximizes charges on higher-rate balances.

67 percent of business cards included penalty rates for late payments or overlimit transactions. This means a penalty interest rate can be applied immediately and without notice for any violation, and that rate can last indefinitely on any balance. Consumer cards can only experience this if the account is seriously delinquent. The median penalty annual percentage rate was 29.4 percent.

73 percent included a late fee, and 67 percent of the cards had an overlimit fee. Both fees averaged around $39 each. Unlike consumer cards, penalty fees are virtually unrestricted for business cards.
