Our company bought three fingerprint attendance machines, the price is one in 980 yuan. For various reasons, we want to change it to a punch card machine, but the dealer charges 200 yuan a depreciation fee. 3 sets of 200 yuan depreciation fees, which is normal. The second sale may require the replacement of fingerprint films, and the market prices of the three fingerprint films are similar; If it is 1 200 yuan, that would be unkind.

Be sure to ask before you buy something, and find out your own use environment, otherwise you will always suffer.
