ACS ACR1252不支持Mifare Desfire / Mifare Plus的读取，因此需要使用其他读卡器。以下是使用Python的代码示例，通过PN532读卡器读取Mifare Plus卡片：

import time
import board
import busio
from adafruit_pn532.spi import PN532_SPI
from adafruit_pn532.ndef import NDEFMessage, NDEFRecord

spi = busio.SPI(board.SCK, board.MOSI, board.MISO)
cs_pin = board.D5
pn532 = PN532_SPI(spi, cs_pin, debug=False)

ic, ver, rev, support = pn532.firmware_version
pn532.SAM_configuration()

while True:
    # Check if a card is available to read
    uid = pn532.read_passive_target(timeout=0.5)
    if uid is None:
        continue
    print("Found card with UID:", [hex(i) for i in uid])

    # Reading Mifare Plus card
    if len(uid) == 7:
        key = b'\xFF\xFF\xFF\xFF\xFF\xFF'  # default AES key for Mifare Plus
        block1 = pn532.mifare_plus_aes_authentication(uid, 1, key, PN532_SPI.BLOCK_TYPE_4)
        block2 = pn532.mifare_plus_read_block(2)
        print("Block 1:", [hex(i) for i in block1])
        print("Block 2:", [hex(i) for i in block2])

    time.sleep(1)

注意：使用PN532读卡器需要安装库adafruit-circuitpython-pn532。
