Should i be worried?

Hey guys, first time poster here. I’m selling a console on marketplace for around the general value for local pick up, and had a person message me interested in it Wednesday. Said he gets paid today, so he’ll message me then. Messaged me this morning and said he was good to meet at a certain time, and was still interested. I sent him a picture of the reset console all ready to go with the high refresh rate hdmi cable he was asking about, and waited for him to respond that he was ready to meet about an hour before. He messaged me and said his card got locked up and had to go to the bank in the morning to get the cash out, but still wanted to meet when we both got off. Should i be worried that he might try and give me fake money, and how can i tell if it is?
