Hello,
After going through the project requirement we are highly interested to work on your project .
Following is our understanding
There will be two parts of the system
[i] Front end
-- User opens the URL , and prompted to enter their ID , mentioned on the card
-- System will check the ID from the stored ID at the DB
-- Shows Valid / Invalid message accordingly
[ii] Backend / Admin end
-- Admin inserts / upload the valid IDs list
Please let us know if we are missing anything
Question : Do you have any technology in your mind ? Our quote is PHP / My SQL technology keeping in mind .
We can start ASAP, and hope can deliver in 1-2 days .
Hoping to hear from your end soon .
