Having been sent this way here's a few background details on how the Democracy card (did whoever picked the name have no sense of irony or PR?) came about:
Up until a few years ago there was one and only one "NUS card" which was available to all unions for free. It was intended to serve three purposes:
* A student id
* Access to discounts
* A means to prevent electoral fraud - it had a strip of numbers on it (carried over to the Democracy card shown above) and the idea was that in union elections a specified number on the card would be clipped when you voted, so you couldn't vote again at another polling station
Oh and the card was hard cardboard until the last few years when it went plastic, with a cut out photo laminated in. (In the last few years it did, however, gain a magnetic strip that could be swiped at places like HMV.)
Now this may have worked many years ago but over time the cards were becoming increasingly redundant. More and more universities produced their own ID cards which are a darn sight more secure than the NUS card, using features liking printing the photo onto plastic, magnetic strips, barcodes and smartcard technology. Unions also often co-operated and combined their card in as they wanted to reduce the number of cards in people's wallets. In turn this created a convoluted situation for student discounts where nobody was 100% sure if another student card was valid for discounts and reports varied wildly in all fields (cards used, chains, branches, even individual cashiers were inconsistent). Meanwhile many unions were finding other ways to do their elections.
Some retailers were reported as reluctant to give a generic discount when they didn't get anything back and wanted a standard card they could swipe to build up customer profiles, similar to club cards. (And no, I'm not sure what the issue was with the magnetic strip on last few years of NUS cards unless the lack of compulsory database registration was a problem.) Meanwhile the uptake of the card was poor with many unions having significant stockpiles throughout the year, and resenting having to devote valuable staff resource time at the most critical time of year to distribute cards they couldn't see the purpose of. Indeed some stopped distributing it, adding to the problems. There was also a burgeoning black market in the cards which could have derailed discounts.
NUS did a study several years ago looking into the possibility of a paid for card that had better discounts available only to that card. The market research suggested the students would be *more* likely to take out the card if it had a clear monetary value. Also income for cash-strapped unions that would not only cover the distribution costs but give them a much needed new revenue stream. Meanwhile the paid for card could be more secure and have a better database.
The one problem was that a number of unions, particularly in Further Education and smaller universities, were still using the NUS card for id and/or electoral purposes and were naturally opposed to the idea of paying for a card for basic membership rights. There was also opposition to making *existing* discounts only available to those who paid. So it was agreed to create a second card that would fulfil the membership/democracy issues as well as carrying the existing discount arrangements.
A lot of unions have not bothered with the democracy card at all for the same reasons they had problems with the NUS card, and the Democracy card still costs to distribute. Furthermore with no discounts officially on it the Democracy card becomes more expensive to produce and distribute for NUS.
In terms of the discounts themselves it's my recollection the ones on the old NUS Card were to be carried forward onto Democracy but only until those discounts were renegotiated. The introduction of Extra was a fierce political battle in NUS with the extreme left staunchly opposed (and it's always extreme left run unions that are the places cited as having dire take-up) and this has resulted in trying to run a commercial product by convoluted constructed conference resolution which isn't exactly best business practice.
