The digital age has given us the opportunity to store all sorts of information about ourselves electronically. Let's take a look at one of the current trends in technology that may help emergency responders enhance the care they give to us in the event of an emergency. Review of QR Codes

That makes them very limited in their use and difficult for the everyday user to create. Enter the QR code.
When Denso created the QR code they made it specifically to be open source. Open source means anyone can use it free of charge. What's more, you can go to various websites that will create a QR code for you for free. Because QR codes can represent numbers and letters they can be used to store messages, addresses, phone numbers, even website addresses. While free is good, lets take a look at some disadvantages to QR codes. To read a QR code you need special hardware and software.

Smart-phones are expensive and so are the data plans that you have to purchase in order to use them. The...
