ETickets for Hikashop
ETickets4Hikashop is a GPLed free & open-source extension for joomla and Hikashop Starter, giving the ability to generate, send and manage electronic tickets which can be verified thanks to barcodes or QR codes.
It generates pdf electornic tickets which can be printed by the buyer, and later verified with ET4HValidator and a barcode scanner.
Electronic tickets are regular Hikashop products. All it takes to make them e-tickets is to activate a checkbox and fill the event date and place. After that, every time this product is bought, a pdf file will be generated and sent with the order confirmation.
