Great input by everyone here.
I would just add:
The variable here is if you have multichannel
coin acceptors or not.
If you do not,
tokens will be a BFD because each bay/vac will need a new one.
If you do have multichannel acceptors, all you need is one sign at the
changer, a new dispensing wheel in the
changer (the capability to program the
changer for the new
token, 1
coin instead of 4 per dollar), and the
tokens. I know
Van Brook carries a few standard security
tokens that are ready to ship. At .35 cents a
token you'd be looking at $1,400 for 4,000
tokens, maybe $100 for the hopper wheel, and the sign.
Credit cards require an account to be set up, which can be tedious as well.
A Crypto pay set up for 4 bays would be $2,400 (4 taps and a coordinator), $200 for the "e-receipts" capability if desired, and all related signage in each bay.
I like Randy's advice to not panic, wait for things to slow down to make a more informed decision and use the increased visits to walk the property and check the equipment.
