PayRange is best used for a variety of coin operated amusements not just exclusive to pinball machines.
Many of our photo booths, skeeball, basketball, air hockey, and jukeboxes are using them and are making good money. I know we have well over 100 units. Install for power and I/O (the coin door/direct switch interface board on WMS pinball machines) is very easy with the "dongle", and not obtrusive to other payment methods such as bill acceptors or mechs. Then the unit is properly tested using a technician code using a personal smartphone for connectivity. I/O connections are just as easy on other pieces of equipment.

Those operators that have less than 10 units may not have enough substantial income to make it profitable. You cannot test case with a single install and expect to have good results, as you will acquire very little audit data for canvassing application use on routes. They are best for high traffic zones, and those that are more technology savvy, such as hipster barcade areas or large volume retro arcades. An operator is not going to make any money using PayRange in an old, dark bar that caters to retired men, telling war stories, drinking beer at noon, in their pajamas.

All new AMI/Rowe are not on Payrange.
Old Rockola were added, until replaced, location specfic, some owners still want "older" equipment, although we try to explain advantages. Credit card functions are all disabled. Previous generation Touchtunes are being phased out.

Primary retro arcade has ALL new pinball games with Payrange, along with with arcades such as the new TMNT game, and most high volume games. Older pinball machines is roughly 50% installed dependent on era.

No use for smoke machines I am aware, and of course not ATMs. No coin changers either, where applicable, most of outer locations are responsible to fill their own anyway.
