Okay, so those of you who know me on Facebook know I like Foursquare, the geolocation microblogging app. I also like Android, the phone OS from Google, which has a cool barcode scanning capability. I’m fond of QR codes, which are square barcodes that you can encode URLs, paragraphs, and other strings of text. Bring it all together, and you have a way to scan a barcode to check in to Foursquare. I use an app for scanning to Foursquare called PhiSq available in the Android Market for free. I also use a free site to generate QRCodes from the Foursquare Venue URLs at http://qrcode.kaywa.com/ — copy and paste the Venue URL into the form, and voila: a QRcode that you can import into Inkscape. However, Inkscape has its own barcode generators in the extensions, and I’m sure they would work with the scanner as well.
I imported them into Inkscape, placed them in a grid, with explanatory text, and printed them out. I’m thinking about taping these to the back of my laptop, though you could get the scan right from the screen where you’re reading this. Although, unless you’re also on Rider’s campus, you’ll have a heck of a time getting any points or badges for the checkin.
