You'd better wait until the children go to primary school to buy a point reading machine. First, buy a morning education machine or a reading pen. The point reading pen is more expensive than the morning teaching machine. The point-reading pen is easy to read. Last time I went to Digital City, I saw the quotation from 800 yuan, which was a bit expensive. It is estimated that around 500 yuan is enough. The card reader of early education machine 150-500 or so, the price of different card models is different. Go to the counter and have a look.
