Intellitix (which I've never heard of until just now) appears to be a Hardware solution, utilising RFID & NFC with custom POS systems.
EventToken (AFAIK) is a Software solution, utilising new crypto wallet saoftware on top of existing hardware (smart phones, laptops etc) as POS.
I understand this basic difference, but as an example to illustrate my point -
http://vimeo.com/106775134This video details how the cashless system utilizing these RFID chips functions from an attendee standpoint. They get a bracelet that is their ticket, they scan it to enter the festival grounds, they upload money onto it (either from home beforehand or at one of many POS systems throughout the grounds), and they scan it for all expenditures.
So for example, from a festival attendee standpoint, the two seem about the same.
Option A - Purchase CryptoStock coins (beforehand or on-site) and spend them using my phone or some other existing QR code compatible hardware.
Option B - Purchase Festival Tokens (same virtual currency idea, also beforehand or on-site) and spend them using my bracelet RFID hardware (which I must have anyways)
From a vendor standpoint you may have an advantage, as I was not able to immediately find any information on the processing fees associated with Intellitix but I would assume they would be higher than 1%. Vendors are not the ones who will be making the decision to implement this technology though.
From an organizers standpoint, I find this concept very interesting and it has been proven that cashless systems have many benefits over traditional methods. Thus your idea definitely has merit and is coming from the right direction. I believe Intellitix / Intellipay will cause you some problems though, as they have a proven track record and seem to have provided a solution to the same issues that EventCoin looks to solve.
If there are any advantages of the EventCoin idea that I have missed I would be interested in learning more, but if you have not previously heard of Intellitix I would advise you check these links out for more info, as it seems to be very competitive in nature.

To do this using blockchain decentralised technology is a lot cheaper than doing it through a centralised RFID system, as every festival goer is supporting the newtork for you. It's also quicker and easier to implement and requires less hardware.
Advantage - lower costs, simpler to implement. Cost and simplicity is at the heart of any business and your right, its not the vendors it is the organisers. I realise intellitix have a bit of a jump on us, and we have much more ideas going forwards (sorry bored of can't release for legal reasons now) but if a festical organiser is faced with 2 systems that can provide a similar end result (and there is no reason ours can't be as advanced as theirs) then, as long as both can prove competency) the organiser with go with lower cost and simpler logistics.
You can still get all the reporting etc that you can get from intellitix by extracting data from the blockchain. You can top up anywhere, no need to to go a top up point, once you register your debit / credit card you can just do it in app.
I can't go into the other advantages until later.
This is a serious project, people on here don't seem to realise the money involved in cashless event systems and access management but it is huge and it is an absolute perfect fit for blockchain.
