Different countries offer different levels of protection. In the UK, for example, the bank is jointly liable with the merchant for purchases of defective products over £100.
Many credit cards offer rewards and benefits packages, such as enhanced product warranties at no cost, free loss/damage coverage on new purchases, various insurance protections, for example, rental car insurance, common carrier accident protection, and travel medical insurance.
Credit cards can also offer a loyalty program, where each purchase is rewarded with points, which may be redeemed for cash or products. Research has examined whether competition among card networks may potentially make payment rewards too generous, causing higher prices among merchants, thus actually impacting social welfare and its distribution, a situation potentially warranting public policy interventions.
A credit card issuing company, such as a bank or credit union, enters into agreements with merchants for them to accept their credit cards. Merchants often advertise which cards they accept by displaying acceptance marks – generally derived from logos – or this may be communicated in signage in the establishment or in company material (e.g., a restaurant’s menu may indicate which credit cards are accepted). Merchants may also communicate this orally, as in “We take (brands X, Y, and Z)” or “We don’t take credit cards”.
