Our expert advises

The module is a clone, which can be seen from the text on the product as RFIO, not RFID, in addition, its SPI bus address is 0x88 and not 0x92. This is manifested by changes in the antenna arrangement, where the capacitors should be placed in a different order. You should replace the capacitors C6 with C8 and C11 with C9 so that C6, C7, C10 and C11 have a capacity of 15 pF, while C8 and C9 180pF, this procedure will restore a greater range of reading cards and key fobs.
