Time Cafe Table Management Software?

So this is a time cafe concept where the customer arrives at the cafe and there is an option to scan the QR code to select their requirements as need. Tried many POS softwares but none seems to have an option that suits this need. The basic flow works as follows:

1 – QR Code Scan

2 – Website opens up with reservation options.

3 – Show available tables and ask for time requirement (1 hour, 2 hours etc)+ number of people,

4 – Once confirmed, show menu to select the food.

5 – Auto send check in SMS with wifi password.

(Time starts in dynamic manner than static time slots. For example, customer 1 came in 5:13 PM, so the 1 hour slot will end in 6:13 PM.)

6 – When 75% of the allocated time is over, send an automated SMS to reminding the customer about the limit and give an option to extend the time slot by half hour or 1 hour increments with discounted pricing.

7 – Ability for the customer to checkout with E-Bills and payment Gateway.

(So probably need a custom time slot preview in order for the next customer to see it in dynamic time than fixed time slots such as 5pm – 6pm like in many of the POS.)

Any Help is appreciated. Thank you.
