I'm often asked what I think will be the "next big thing" when it comes to technology and Jewish education. Recently, I've been focused on QR codes. You know those odd little squares that look like a cross between a thumbprint and a bar code? Scanning that QR code automatically provides you with information about whatever it was that you just scanned. A lot of information. Scan a book and immediately be able to search inside its pages or find the lowest price online to purchase it.
