Essentials Economy Plugin

Afternoon or Morning, working on my server where people use a sign once, by charging them $1 in game currency. But the max they can carry is $1 (I want this). And on a new player to server they also get the $1 (which is correct) but once they die. and rejoin I would like them to be given $1 again. Or a way to get it like walking on a pressure plate. If this is the wrong forum area let me know, Thank.

Overall question. how can I get someone to have $1 added to account upon respawn. Pressure plate or just added automatically would be great.
