Pet Hub, a Washington based company, offers dog and cat ID tags with a QR code - that funky square barcode that can be read by your smart phone. When someone scans the code they are taken to your dogs very own web page. You keep this page updated with their current information.
The individual web page gives you room for a lot more information than would fit on a tag. You can list the typical name, address and phone number, and also your veterinarian, any medications, allergies, important behavior issues (like "can climb fences!" or "doesnt like cats"), reward info and even photographs. Update the information anytime you want - if you move, if their medications change or anything else - you are in charge. The Pet Hub tag also features a unique web address that can be manually entered, in case your pet is found by someone less technically inclined.
