Things I need you to test:
On the Account page can you successfully create an account with your email and password or email and requesting the magic link which emails you the link to complete the login. Can you sign out and back in without any issues? When you set up your account and it shows you logged in with your email address you’ll see Collector’s Pass Active in bright green at the top of the account page and the scan coin page.
Scan page is where you can upload your challenge coins and include vital meta data that will help tell the story of your coin. We’re trying to build a challenge coin exclusive database that’s searchable. The coins have meaning to each of us and every coin tells a story. We’d like collectors to share their collection with the community and tell the stories behind your coin and what they mean to you.
As you upload coin images and metadata for each of your real physical coins, you want to be as detailed as possible. Look at it like a time vault. You will remember the key details as soon as you see and hold the coins. Even if it’s 20 years later! The My Coins page is your personal collection. The page is set up so the coin rack has 4 coins per row.
When you fill the first screen, your coins will become scrollable and you can scroll through EVERY challenge coin you own in one display. No need to by additional wooden racks, This expands to infinity. The display will grow as you add coins to your display.
Your coins will be featured on the browse tab feed where all of the uploaded challenge coins can be found. You can touch any coin to open it and see both sides as well as any metadata the uploader included, to build the coin’s backstory.
In the top left corner of every coin on the browse page is a challenge symbol. Like that coin and want to do a friendly coin check and put your coin up against theirs? Tap that button to initiate a challenge. Then your my coins page will open and you can scroll and tap the coin you want to challenge the person with. For the next 24 hours, your challenge is visible on the challenge page with a simple vote for the coin you like the best. Each like is tallied and displayed on your coin images in the my coins page.
Currently working on the ability to search the database to find entries by photo or camera image comparison.
