WAP stands for Wireless Application Protocol.
It is a set of communication protocols that allows wireless devices such as mobile phones and PDAs to access information over a mobile wireless network.
WAP made it possible for mobile users to browse the internet, check emails, and use online services on small-screen devices before smartphones and 4G internet became common.
It was especially significant in the early days of mobile technology because it standardized how content could be delivered to wireless devices.
Although modern smartphones now use advanced mobile apps and browsers, WAP laid the foundation for today’s mobile internet services.
In banking, WAP helped early mobile banking services by enabling secure access to account information and transactions via mobile phones.
