WARNING- same barcode, different gyms!
Just a note of caution for those using barcode entry. We found that some customers were mistakenly using their entry card from another wall at our wall (and vice versa). Because both of us were using the same range of numbers for our barcodes and are in the same city (London), we've got a substantial amount of overlap.
So... if you're setting up for the first time I'd recommend making sure you use a prefix unique to your wall!
Wish I'd thought of that before ordering 30,000 more key fobs (sigh).
Andy/Amy- maybe you can include this tip in your next issue of setup guides?
