 * Hi there,
 * You can limit check-ins within Tickera > Ticket Type > Check-ins per ticket.
   
   Just put 1 and ticket will be valid only once 🙂

 * yes i already did it but i tried to chech in the same ticket after some second
   he say “succes” if i wait 1 or 2 minutes betwin two check in i don’t have any
   problems.
    fore example if i have a family that have 2 children and they have
   the same ticket they can cheat me because the sistem is slow to update the checkinned
   ticket i can resolve or there aren’t ways to resole this problem?

 * Hi there,
 * In regards to the first question, please check if you are using any caching system
   on your site, it can cause this issue. To fix this, you will need to exclude 
   some pages from caching. Here you will find the instruction – [https://tickera.com/tickera-documentation/configuring-caching-plugins/](https://tickera.com/tickera-documentation/configuring-caching-plugins/)
   
   Second issue can be related to the caching, as well. Please let me know if this
   was the cause.

 * Do you are able to suggest me a plug in for cache?

 * Hi there,
 * We are so sorry for the delay in response.
    We would recommend W3 Total Cache–
