Cufflinks: One of the classier ways to wear your codes are these resin cufflinks that can be personalized with a message for a special day or event, like a wedding. The cufflinks themselves measure .75 inch and there's also a silver sterling option, also customizable to link to your website, Facebook page, business details or text message; up to 150 characters can fit onto the 2cm x 2cm square faces.
Jewelry: Futuristic-looking QR code rings have been seen in the wild for a while now, and their popularity has extended into necklaces that convey sweet pop-culture messages. A particular stand out is the red, laser cut acrylic necklace that scans to get a message of "Will you marry me?" - a unique way to propose in the technology age! Other noteworthy mentions include the Harry Potter "Always" glass pendant and the GEEK bottle cap necklace.
Belt Buckle: Another way to have your QR code always at the ready is to place one in a belt buckle. The face is sealed using resin, the buckle is nickle plated and the included belt is 1 ¾ inch. The codes themselves can contain text, numbers or web site addresses.
Scarves: While the darkly stylish scarf from Lendorff Kaywa has been around for a while, it now has some competition from machine knitters at SternLab and silk painters on Etsy, both of whom have been producing some lovely competitors. Like with any QR code offering, the scarves can be customized to your message, but are also available in sweet "I love you" versions.
Tote Bags: Carry your QR code with you where ever you go with a slick industrial tote bag made from hand-painted aluminum, black leather and copper accents. Or, cut down on your plastic bag footprint by using this canvas tote with an embroidered QR code which can, of course, be configured to any text.
iPod Cover: While sites such as Cafe Press are happy to customize your QR code onto an iPhone case - helpful for any marketing purposes - it's the crocheted and cross-stitched QR cases that grab the eye. The DIY cross-stitch iPhone case kits at Connect Design are mostly seasonal but can be easily repurposed to create your own QR code; likewise the crocheted version is handmade courtesy of Etsy seller MyHobbyShop, however, these are only available in one of seven messages.
Tshirts: QR codes have been gracing the fronts and backs of tshirst for some time now (with the social media link/ Facebook ad being one of the more popular options), but now that it's increasingly easy to create your own QR code more and more tshirt fans are incorporating the matrix barcode into their designs, from a Keep Calm and Scan Me style, to a black-and-green Android version, somewhere there's a QR designed T that's right for you.
Buttons, Badges, Patches and Bands: In the world of marketing, merch is a key component and QR codes have really excelled in their usefulness at connecting an audience to a website, service or product. So it's no wonder that one of the most customizable technology advances appears on a multitude of buttons, badges, patches and wrist bands - all of which are easy to mass-produce and make great swag gifts to promote an app, band, website or business.
