Must Know These : The development of technology, especially in gadgets, continues to increase. One of the features that smartphone users are looking for today is NFC. NFC stands for Near Field Communication. This term denotes contact-free data transmission using radio frequency identification (RFID) technology. The worldwide standard frequency numbers at 13.56 MHz and provides a transmission range from five to ten centimeters. Basically, the NFC sector is divided into three different modes or functions. NFC Function in Smartphones Must Know These
1. Card Emulation Mode
Your smartphone takes over the function of contact-free cards. This way, you can open, for example, a smartphone-compatible door in a hotel or get access to your company and the respective times are also recorded.
Your smartphone is also replacing credit cards in conjunction with other payment solutions. You just put your smartphone on the cash register in the reader and the financial transaction is processed.
2. Reader or Writer Mode
Using this mode, the contents of the NFC chip will be readable by your smartphone. This can be used for example for so-called Smart Posters. Smart Poster is a technology that changes posters that were originally static to dynamic.
You can take advantage of this application by attaching your smartphone to the chip integrated into the poster, the mobile web page is opened and you can directly buy tickets to the concert in question or make a donation. Thus, your smartphone serves to read out the chip in this application.
3. Peer-to-Peer Mode
In this mode, communication occurs between two smartphones or tablets. This means that data, contacts and pictures can be transmitted from one mobile device to another. Here are some of the key benefits of adopting near-distance communications technology to accept contactless payments at your point of sale: Convenience and ease of use Consumer expectations for convenience are always on the rise.
Close-range communication makes payment transactions easy, as consumers often just need to pick up their phone or NFC card to make a payment. Unlike EMV transactions where consumers have to learn to dip, and wait, it’s no wonder that mobile wallets that use short distance communication are gaining popularity.
The increased operational efficiency of NFC enables faster transactions which reduces the amount of time customers have to wait in line as well as the time spent at registers. NFC helps speed up payment paths, increasing customer satisfaction with your business. This clearly represents critical operational efficiencies for businesses that turn high transaction volumes at checkout. Ease of implementation
1. Share Contacts
NFC allows users to send phone numbers and contact details to other phones without having to enter details manually. To do this, you can open the Contacts you want to share, then touch both phones together and choose to send. The contact you send will be saved to the Contact List on the other device.
2. Send Image or Video
To send a photo or image from your phone to another device, open Images in the image app of your choice, place the backs of the devices together, then press Send when prompted.
3. Send Documents
If you want to send online books, PDFs, or other documents, then you can use Android Beam. Find the document on your phone, then open the Settings menu and select Share > Android Beam. Bring the two devices closer together, then press Send when prompted.
4. Share Apps
You can’t send apps directly to someone else’s phone. However, when you open the app and touch your phones together, you can direct them to open the Play Store app so they can download and install it themselves. If the other phone already has the app installed, you can open it by sending it from your phone.
