Good day!
We have a project(vending machine)
We need to have wireless functionality that sends or updates database to the laptop. This database refers to the stock of the vending machine.
How can we do this? Sends or update database for every transaction.
Bluetooth?
WiFi?

Yes, sir. Wifi. We need that microcontroller updates database for every purchase
Maybe the simplest solution would be an Arduino Yun which has WiFi as standard and a Linux processor as well as the Arduino. It would allow you to program the WiFi stuff using Python with much greater versatility than using, say, an Arduino Uno with a WiFi shield or an ESP8266 WiFi module.
An Arduino coupled to an ESP8266 would be the cheapest solution.
In fact an ESP8266 can be used standalone without any Arduino - but that is beyond the scope of this Forum.

Thanks a lot Robin! Is it possible to update using that module out database? For example, updating mysql database.

Where will the mysql database be hosted?

I guess you need to consult a specialist.
Apache 2?
I am not understanding the logistics of this.
You mention wifi. Were you planning on paying for internet at each vending machine location?
If it was me, I'd send a sms to a central location. Have that central location have the ability of updating the database. Keeps the hardware at the vending machine to a minimum.
