App to replace a hotel key card commonly given to hotel guests when they check in at a hotel
1. Design a smartphone app (Android, iPhone, Windows) to pick up hotel key programming so one can replace the hotel key using their smart phone app.
2. This can be done in two possible ways:
a. Take a picture of the hotel key magnet strip or bar code with your smartphone which would then activate the hotel room same as the hotel key card to open door. Or,
b. The hotel front desk scans the smartphone same as they would scan the hotel card and the app is activated same as the hotel key card to open door.
Please tell me if this can be done, how you would do it and how much would the programming cost.
