QR Codes In JiouFen

Jiou Fen, a popular tourist spot in Taiwan seem to have quite a few of the shops and restaurants nearby implement QR Codes. Previously I have only noticed the barcodes on their website, but visitors seem to be taking notice of the strange looking symbols and someone has posted an actual sighting on his blog. The QR Code appears quite large, perhaps containing a lengthy text intro of some sort, which makes one wonder why not just print the text itself? Of course, it is possible that they are using the codes for other marketing purposes as well.
