Hello I wanted to know if the security deposit can be left in cash. Since my card does not have enough margin for that

Only card ...... and it seems to me that the other card is not possible .... I really do not know

My wife already rented a car from January 19 to January 30 with a credit card from hers. But the owner of the rental will be me. Can her credit card be left as collateral? Although at that time it does not have a credited margin since it is credited from the 24th,

Credit card only

I don't know that
