<human>:  What is the difference between an unsecured and secured credit card?
<bot>: The main difference between an unsecured and secured credit card is that an unsecured credit card is granted by a lender without any form of collateral, while a secured credit card requires a deposit that acts as collateral and is used to secure the loan against default. An unsecured credit card may also come with higher interest rates, while a secured credit card often has lower interest rates. Additionally, secured credit cards may have higher credit limits, since the lender knows the deposit limits the amount of risk.
