Those systems are a big waste of time and effort IMO. Personally, I would NEVER patronize an establishment that used them.
More and more of the establishments are using them now.
From a business standpoint, I think they're as brilliant as the token. Quite a few people don't use up their credits and the cost of the card is probably much less than any number of tokens. It's a recipe for pure profit.
Looking at the SVCS I've seen, they don't seem to cut into existing doors, they appear to be direct drop-in replacements. From what I can tell, the installation of the readers appears to be reversible as
described in this article. I would hardly call carving up the coin door a reversible process.
I'm old school and prefer the tokens, but the reality is that these things are going to be hitting the collectors market soon enough and there's going to be an entire generation of kids who consider these readers the norm. Also, despite any restores I have in the tubes, networking my cabinets is on my ToDo list. It isn't a much bigger step to add in card readers.
