Agree with other posters who say this will be the thin end of the wedge.
It wouldn't be long before benefit cards would be rolled out to everyone on benefits excluding pensioners and disabled people.
The results would be more people plunged into deeper poverty.
There would only be a few large companies who would be able to accept the cards. The extra systems needed to be put in place to process these cards and the restrictions placed upon the cards would mean recipients of these cards probably wouldn't be able to shop at;
Charity shops
Boot sales
Small corner shops
Facebook sales pages
Ebay
Market stalls
Independent travel companies
In fact, any small business.
I'd imagine you wouldn't be able to use the balance on these cards to pay companies such as mobile phone companies for contracts, sky, amazon, play.com, shops like 'the entertainer', certain clothes shops.
In fact, it would probably be easier to name the shops/companies you would be able to use.
There would be too many supporters of the DM variety who would agree that those pesky people on benefits shouldn't have any business shopping at any of the companies I've named above and more besides.
The only 2 purposes it will serve is to vilify the poor and create a black market where the cards are sold for cash for less than their face value and thereby making the poor poorer but doing nothing to control what poor people spend their money on.
As you can tell, I don't agree.
It wasn't long ago that the benefit cap was set at 26000. I knew then that the cap was just the beginning. Now we are told that after the next election, this will be reduced to 23000, and I believe it will be reduced again and again after that until it is not possible to survive on benefits unless you are a pensioner or on disability benefits. Considering more and more disabled people are being condemned by ATOS to look for work they are not able to do, it won't be long before disabled people will be subject to this hell as well as anyone else on benefits.
