An Excellent Place for QR Codes in Jewish Life: Kashrut Certificates

While on vacation in Florida, a difficulty presented itself to us: we would see a kosher certificate with a rabbi's name on it, but know nothing about the rabbi. Thus, even when there is a kashrut certificate (תעודת כשרות), that gives the [potential] consumer very little information regarding either the kosher supervising agency or the rabbi providing the supervision. Although for big cities, people may frequently not know who the particular rabbis or certifying agency is, but especially so when travelling and one has no sense of the local rabbinate. Now while one could do a quick google search on one's smartphone while pondering the restaurant, there could be an easier way of informing the consumer.

Just as I have suggested for zoos and for Jewish communal agencies, it would be helpful if, on the kashrut certificate, it would include a quick response (QR) code (it looks like a two-dimensional barcode). The QR code that would appear on the kosher certificate would send the potential consumer to a webpage either on the supervising kosher agency's website, the supervising rabbi's website, or the restaurant/supermarket's website.

(As an aside, this would also be helpful in the case of the Tav HaYosher, which would send the potential customer to either a page with information about the Tav HaYosher in general, a Tav HaYosher page with information about the particular restaurant, or a page on the restaurant's website.)

The inclusion of a QR code (or Microsoft Tag or any other similar products) would be a quick and easy way for informing customers and it wouldn't be much more difficult to include on the kashrut certificate.
