The text of the original in Russian


I collected three pieces, although I have to ruthlessly discarded or not taking, because the permanent separation of attachment to certain stores virtually none. But others, especially the beautiful half of humanity, a few dozen. This leads to increase the size or purse or carry a business card that is not very well have an impact on the size of women's handbags. 
The proposed idea - a universal discount card, the type payphones. A man enters the shop which wants to start a discount, getting a card, which he had only one - sells a scanner reads the information and thus to activate the card in its network. 
    A piece of plastic, a chip, a scanner and a database, which handles all information, including bonuses and interest rebates. Each shop / network connection for the money through the internet (wired, wireless, it has the details). Monopoly on production of cards, hardware, and a centralized database in the hands of the manufacturer. Cards are sold major shopping networks with their logos and their corporate colors, to «fuse» PR and the first installment of a purely symbolic price. and smaller retail chains and stores are connected to the database by creating its own database ID. There is very strong in electronics, but I think enough has already been developed by the industry to offer for sale or manufacture of a chip that will store an array of information. In addition to all this information is variable, ie it is processed at the hardware part of the holder of the business, a kind of servers. A man comes into the store, the information is read from the card scanner and is given the percentage of discount - purchase made. At the same time, information on buying transmitted to the server, where the amount spent on it plus a database of this store. If the smaller stores do not have a permanent connection to the Internet, it is sufficient to connect at the end of the working day to transfer data. 
   The benefit for buyers is obvious - one card, and no bloated wallets and business card holders do not need to fumble for the bags and wrestle with what a stack of discount cards to take with you today. With the increasing power and functionality of these cards can be had other, more complex functions. 
Of course initially it is not very like the owners of shops, but on the other hand - the benefit is obvious, they do not need to spend money on the endless acquisition and production of cards. In addition, the payment can take it to the percentage discount - let the person 15% discount, but when you use the card it is 14.5%. This is fine, but 
Convenience cut spending in half per cent discount. In supermarkets, where discounts of 1 to 5%, the percentage of payments for services less. 
The owner of the business earns 
1. on the sale of cards 
2. for activation of new 
3. fee or percentage may be, but mikroplatezhey the terms will be quite profitable. 

Unfortunately for fans of someone else's idea or crook earning plagiarized material is already protected, so to use the ideas you have to contact me and discuss 

P.S. In product design, and production of the cards might interaction, because there are proizodstvennye capacity for the production and discount cards. The region of production - Donetsk (Ukraine)
