The issussing of annual membership cards has been trialled several times over the last couple of decades, all with disasterous effects, from memory the last time it was used they were offerring silver, gold and platinium cards, which allowed the purchaser to eithier a unlimited or restricted number of games per day, week, month or year depending on the card purchased.
It has long since been a capability of centres with computer scoring to incorporate a frequent bowler reward or membership card program, the first fully blown computer scoring system from the early 80's, the AMF accu-score indeed had a computer program to cater for such events.
The membership card promotion, failed miserably, the majority of people who purchased these cards were league bowlers who practised regulary anyway, they insured they got their moneys worth from their membership card.
When the figures were calculated, it was found that not enough cards were sold and not enough cards were used on a less frequent basis to offset the high useage of the regular bowlers, thus, the cost of cheaper game rates, the majority of card holders were bowling games for well below the current cheapest game rate, some bowlers were reported to be bowling games for less than a $1 per game.......clearly these prices could not be sustained by any centre.
To make matters worse, their was also no notable increase from other revenue sources, the snackbar, bowling equipment and bar sales showed no increase.............it was lose:lose proposition for the bowling establishments.
All the computer scoring sytems of today, Qubica (now part owned by AMF), Biggs (computa-score) and AMF have the capabilities to run a frequent bowler or annual membership program with their computer system, however not many, if any use this function.
IMO it would be a foolish move by a brave company to try and sell membership cards for Tenpin bowling.................unless the bowling industry can turn things around, and in a hurry, I just can't see it happening.
