vouchers is now issued in the form of gift vouchers (alternatively gift vouchers), or gift vouchers . The two are essentially the same except that the cards automate the checkout and accounting processes. Cards usually have a barcode or magnetic strip, which can be processed through a standard electronic credit card machine.
In the late 1980s, the term scrip evolved to include a fundraising method popular with non-profit organizations like schools, bands and athletic groups. With scrip fundraising, retailers offer the gift certificates and gift cards to non-profit organizations at a discount. The non-profit organizations sell the gift cards to member families at full face value. The families redeem the gift cards at full face value, and the discount or rebate is retained by the non-profit organization as revenue. Great Lakes Scrip Center, the US’s largest broker of scrip gift cards, reported that more than 4 million US households and 15,000 non-profit organizations use scrip fundraising. Canada’s largest scrip fundraising company, Fundscrip, demonstrated scrip’s popularity by boasting a 75% repeat purchase rate among groups seeking to easily support their respective causes.
Gift vouchers are increasingly being offered as consumer incentives at no cost or for a substantial discount. For example, reward points given for the use of credit cards can be exchanged for a variety of gift cards and some companies will offer high value gift cards at a discount. Gift vouchers are readily available at a discount using online trading services.
There are websites where users can trade, donate, buy and sell gift cards. Sellers use these websites because the gift vouchers is not to a store of their liking, and buyers because this provides opportunities to buy these cards for less than they are nominally worth at the business. There are other websites that sell a collection of third party gift cards; businesses offer credits to these websites for employee incentives, usually in return for a discount; however discounts for consumers are rarely offered.
An increasing concern with gift cards are their environmental impact. Studies  have shown an estimated 1.6 billion plastic gift cards are produced each year, which requires over 9,000 tons of plastic and emits 33,260 tons of carbon dioxide.
