Automatic Ticket Dispenser

[gurntham]

I would like to create a “token system” using raffle tickets to reward my children for achieving good grades, completing chores, etc.

What I envision is a lockable box with a ticket dispenser, a keypad, and a 2-digit LED numeric display so a parent can enter the number of tickets to dispense. Similar to this:
 

I would like to make it as compact, simple, and affordable as possible.

It would be great if I could also “password protect” it so a kiddo doesn’t just help themselves. Fingerprint scanner??

I’ll be honest… I’m a total noob.  So it would be immensely helpful if I could assemble a step-by-step guide on how to interface the components.

Here are some links to components I’ve found so far:
Ticket dispenser = https://ebay.to/2YLYCsJ or https://ebay.to/2YIHLY6
Numeric Key Pad = https://ebay.to/3DGePii or https://amzn.to/2YHmE8o

I welcome any suggestions, referrals, and guidance.
Thank you for your help!

  excelsior! 

 Looks like a good idea; My first impressions of this is to find a real one, and adapt
that to what you need. If they are too expensive, you can get the plans to see how
the mechanical works, then follow the plans from there.

  The real issue here, is the control of how many tickets are awarded for a specific behavior,
and how will the tickets be used to work toward the prize?    Is  it a "get out of trouble" ticket?
Is it candy? is it a game console? Is it a trip to an amusement park? Pizza on Friday night? 

   incrementing the tickets for a specific reward implies some kind of control code. Once the control
code is functional, then "map" that to the mechanical control to increment the tickets. 

  Sound like fun, no matter what - I suspect the kids will be giving you "hints" of how big to make the
prizes!!   

  Good luck!
