A summoner ID Card: A suggestion for Riot, a sub-product of LoL.
After the end of season 4, all player get frame and summoner icon according to their achieved rank in the season. As a marketing student, I was thinking would this possible to visualize the idea in the real world. As I am a member of some kind of special interested group, I have a membership card published every year just for the sake to recognize you are a member, which is without any other uses(maybe to show off or to show their loyalty towards the game they loved so much). Although it is so useless, it show your status, people are willing to pay for that card and put it in their wallet.
Therefore, my idea is to create a summoner ID card based on the rank you have achieved last season. And it is better to limit the sale period to 1 to 2 months after the end of the season.
The quality of the card: is better to make it look nice and durable. (like a bank card)
Design: The frame can be according to the rank you achieved, as well as the icon on left (as shown in the attached file) It can include your summoner name and a icon of your ranked most played champ (the data can be achieved from the database of server) which can show every card is tailor made with heart.
Recommended selling price: 7-10 USD/ 5-7 GBP/ 50-70 RMB
Method of Delivery: by local mail service.
Future development: "Maybe" in the future, the card can embed a electronic chip which is connected with your lol account, and used in the real world. Like those game card you used in arcade, you can connect you card with some arcade game machine to play and save the data in your card and synchronise to your lol account. :D
