Shenzhen Shekou Ferry Port-Paymant options

Hello, I have to go from Shekou tok HK airport,but i dont know how can i pay there. I got many different information about this. I can use my mastercard there, or i can just pay only cash?
( When im arrived to hong kong, i used my mastercard, to buy a ticket to Shekou, but yes it was on hong kong side…)
