Cashless Catering - In the event of server failure...
We are currently in the middle of trialling various Cashless systems, but we are being told mixed things about the level of operability at the tills, should the server fail/connectivity be lost.
In simple, I am wondering if any of you guys with cashless systems already installed have been in this situation yet?
If so, do you have the ability for the tills to still operate in terms of students lookups, chargeability etc? Some claim to have a local database at the till end which then syncs back to the main server db once everything is back online, giving some functionality when you need it the most. (I appreciate that with the live link being down would potentially cause students to be overdrawn, spend what they don't have etc, but is in our opinion a better option than students not getting served due to chaos/a paper based system being used for upto 1000 transactions...).
I have been told by other competitors that this isn't the case, and whilst it's claimed, it's nonsense. Would be great to hear some real life experiences!
