Mobile phones have come a long way from its origins in the 1970s. From bulky screenless tools that only had a keypad and an antenna to the slim, glossy smartphones of today, phone users await what the next upgrade would be.
In the early 2000s when brands such as Nokia and Motorola were in everyone’s hands, people had to send files using MMS or connect their phones to computers via cables. Now, we have multiple options in sending files—be it audio, video, images or PDFs.
NFC Direct explains that near-field communication (NFC) works when a device transmits a signal to send data to another device. As the name implies, the devices must be near or touching each other for the technology to work.
NFC does not just work between two powered-on devices; it can also work with passive devices, such as travel card readers.
Bluetooth is a short-range wireless communication technology that connects two electronic devices. Unlike NFC, Bluetooth is not limited by distance—it can reach over thirty feet. The trade-off of this is that it will need a power radio to work, while NFC does not.
Another way of sending files is by emailing them if your mobile device has internet access. Email apps, such as Gmail or Yahoo! Mail, and messaging apps, such as Skype and Facebook Messenger, can transfer files between mobile users.
Infrared is the technology used in television and remote controls. The red light indicates it in the remote control that you must aim at the TV to change channels.
Infrared started as the file transfer option for low- or mid-range phones that did not have Bluetooth. Like NFC, you had to place the two phones close to each other to transfer images and other files.
Smartphones and other mobile devices have undergone a lot of upgrades since their inception in the 1970s. Through the years, people have experienced different methods of sending files. These include infrared, Bluetooth, mobile internet and NFC. Without these technologies, we would not be as connected as we are today.
