I'm using two components that depend on spi ccommunication ( MRFC522 & SD Card Module), apparently i can use both together and the diference will be the cs e ss, however, when i connect them together the rfid didn't read any card. Can somebody help me?

Welcome to the forum

Please post the sketch that does not work, using code tags when you do, and a diagram of your circuit showing how the components are connected together and powered

if the SD card is sharing a SPI bus with other devices there can be problems, see Sharing the SPI bus among SD card and other SPI devices
what microcontroller are you using?

There are such SD modules that has an incorrect PCB design and doesn't allow their use on the same SPI interface with other SPI devices/ The same about some MRFC522
