Gift Card Exchange Website

It's a website that facilitates the trading of gift cards. You can post the amount on the gift card and what it's for, and then search for someone to trade with. Instead of trading the actual gift cards through the mail, the website would transfer the balances on the gift cards to new gift card numbers and those new numbers would be emailed to the users when the trade is made. You can still shop at brick-and-mortar stores with just the numbers rather than actual cards because most stores are able to type it in manually at the registers.
