I came across JustOneClubCard.com about a year ago, and now I get asked about it almost every time I use a “loyalty card” at the store.

Why? Because all of my loyalty cards on on one laminated card in my wallet.

JustOneClubCard.com is a free service that generates a printable image of all of your shopping cards. All you do is print out the page, cut on the dotted lines, and laminate the folded paper (and I use “laminate” loosely — I did mine with packing tape).

The resulting card was a bit smaller than a standard US business card (the short side is about the same, and the long side is significantly shorter), but I think that depends as much upon your printer as the site. I had to print a couple of them before I got one I liked, but that was entirely due to me being picky about the placement — and bad at packing-tape-lamination.

After a year, I still love the concept. There are only a few annoying things about it:

• You can only place eight cards on each printout, so if you have a lot of cards you’ll have to make more than one. It is free, so this isn’t really a problem.
• Some cashiers have a bit of trouble comprehending what you are giving them. I’ve never had it rejected, but I have gotten some confused looks and requests for directions.
• The biggest problem I’ve had is with people that don’t realize that you have to cover up the barcodes you don’t want to scan if you are using one of the built-into-the-table laser scanners. Handheld scanners are more precise (though I usually hold it up with my hands covering the other codes rather than hand it over, even in that case). Sometimes that has resulted in confused checkout machines, but not very often.

If you are like me and don’t like a bunch of stuff on your keyring or in your wallet, I highly recommend this site — but only if you don’t mind conversations in the checkout line.
