How to restrict a shop's wifi to let customers to do only UPI transactions on it? Possible? (1 Viewer)

Today I went to a convenient store...
Shopped, Dropped (in cart) and Moved to Checkout.
But Data exhausted in my mobile internet.

So, Is there way to let the users (Customers Like Me) to connect to a hotspot just to do only UPI transactions?

How to restrict a shop's wifi to let customers to do only UPI transactions on it? Possible? (Strictly UPI only. Otherwise customers will come to the shop for free wifi to watch porn and all)

Since websites can be blocked with network settings, I presume you can restrict to allow guests access to only a certain web address. You have an IT manager?

There is such a thing as a "stateful" firewall that can place protocol or target-address restrictions. Basically requires you to build a set of rules that include info about an IP address and/or protocol and the word ALLOW or DENY. (An all-or-nothing approach.) These firewalls work in a specific order, so the "ALLOW" entries come first and then as the last entry, you put something like TargetIP=ANY, Protocol=ANY DENY so that if the traffic is not among the things you allow, everything else is blocked. The real trick here is getting a complete list of what you need to allow, because that DENY is going to shut you down fast.

If you put the Wi-Fi hot-spot on the OUTSIDE of the firewall so that traffic has to pass through it to get to the site's router, then extraneous requests would be disallowed. It IS a bit tricky, and there are other firewall-based solutions that put the firewall elsewhere in the virtual circuit.

Or just don't use abbreviations that your audience may not know ... Communication 101.
Sorry, but it's very valuable to adopt this rule.

At work years ago I decided to just stop doing it. Those who do it, invariably 10% of their audience doesn't know what it means. That then spawns 20 more emails - and on and on. In some cases there are people at work who use abbreviations because they feel cool when doing so - but really the coolest thing is for your whole audience to understand you

Or it could be the 1998 movie, Under Poopy Implications ?

I wish there were a way to double like a post.

I recall a merger of government departments years ago. A real mish-mash of TLA's.

Three letter acronyms

" A real mish-mash of TLA's."

And, in the context of this thread how can I not ask, what in the world is a TLA?

3 letter acronyms

Oh, that the U.S. Navy would have limited themselves to 3-letter acronyms and short abbreviations. Those that were only 4 letter names were few and far between. Most of what we had was 5 or more letters.

We had RCCPDS - casually pronounced "rickety pids" - Reserve Components Common Personnel Data System.
We had DEERS - pronounces as it looks - Defense Eligibility Enrollment Reporting System
We had OCONUS - Outside Continenal USA
I actually worked for NAVRESINFOSYSOFF, which should have been NRISO but someone else got that first.
The systems I worked ON were the property of CNRFC - Commander, Naval Reserve Forces Command.
For jurisdictional reasons, most information systems fell under SPAWAR - Space and Naval Warfare Systems Command. HOWEVER, with the creation of the new branch called the Space Force, SPAWAR became NAVWARSYSCOM (losing the "SPACE" part).

I would have LOVED to be limited to 3-letter unpronounceables.
