Our expert advises
The module is a clone, which can be recognized by the inscription on the product as RFIO and not RFID, and its SPI bus address is 0x88 and not 0x92. This is manifested by changes in the antenna layout, where the capacitors should be arranged in a different order. You should replace capacitors C6 with C8 and C11 with C9 so that C6, C7, C10 and C11 have a capacity of 15 pF, and C8 and C9 180 pF, this procedure will restore a larger reading range of cards and key fobs.
Included
