The last time I talked to the guys from Happy Owl Studio, they were busy cranking out great-looking leather bags for Apple devices. Now the company is producing the Cashbox (starts at US$750 - $1,500, depending on the payment solution selected for the register), a product that was still in planning back in early '12 and is now ready to give your iPad cash register a solid and sustainable home.
As you'll see in the video at the bottom of this post, Happy Owl uses sustainably grown and harvested bamboo wood that is then cut to precise measurements with a CNC milling machine, laser-etched with a logo of your choice, and hand-finished. The guts of the Cashbox are all industry-standard -- an iPad, of course, as well as a Star receipt printer and a Vasario cash drawer.
The Cashbox can not only accept credit and debit cards through Square, PayPal, or any of the other common iPad payment solutions, but also has a cash drawer for taking the old legal tender as well. One unique feature is the tilting iPad holder that flips from letting a clerk enter an order to a customer's view of the transaction for signature.
The Cashbox certainly appears to be a lot more sturdy and usable than the upcoming "Stand" or the existing Business in a Box solutions from Square. If you're looking at an iPad-based register solution for your business, the Cashbox is definitely worth a look for a solid custom register.
