VoucherPress is a WordPress plugin that allows you to give downloadable, printable vouchers/tickets/coupons/tokens in PDF format away on your site.
Have you ever wanted to give away vouchers, tickets, coupons or tokens on your website? If so this plugin is for you. You can create a voucher with whatever text you want, choosing the layout and font from a range of templates (you can also add your own templates). Vouchers can then be viewed, downloaded and printed from a specified URL.
There are shortcodes to add a link to a particular voucher, to show an unordered list of all your vouchers, or to show the registration for to request a restricted voucher.
You can require visitors to provide their name and email address to get a voucher. If an email address is required an email is sent to the address with a link to the voucher URL. Each voucher has a unique code, and vouchers that have an email address associated with them can only be used once, so once a registration-required voucher is downloaded it can't be downloaded again.
