There is an update on the Hypertag wireless proximity marketing services:
1 - Their prices are flexible based on quantity of tags ordered and rental period.
2 - More importantly, they have just launched a new product, the Hypertag 5, which can be bought outright instead of rented. Paying a monthly fee, they can refresh the content over the period of the campaign and daily check how it is performing (how many downloads, how many audience alerts…)
Great to see ongoing new product development!
