How To Program NFC Tags – 2024 Beginners Guide


Near Field Communication (NFC) is a short-range wireless technology that enables the exchange of data between two devices, or between a device and an NFC tag. One of the most popular uses for NFC tags is to store small amounts of information that can be read by NFC-enabled devices like smartphones. This makes them ideal for use in areas such as product tracking, customer loyalty programs, and payments through mobile wallets.

We are now living in a world where our phones, laptops, cars, and even watches rely on NFC tags to make our lives simpler. So, if you’re interested in learning how to program NFC tags, you’ve come to the right place. This blog will take you through all of the basics of programming NFC tags so that you can start using this technology today!

NFC Tag Programming Basics


If you’re new to near field communication technology, it’s important to understand the basics of NFC tag programming before you start. It is a simple yet complex process with several components involved.

First, each tag has a unique ID that can be read and written by NFC-enabled devices like smartphones. This is known as the Unique Identifier (UID). It is also possible to write data onto a tag which can contain anything from personal identity cards and access control IDs, to digital coupons and contactless payment information.

Next, you’ll need an app or toolkit compatible with your device, that can be used to program the tags with information stored on a computer. For example, if you want to add loyalty points onto a tag for use at a store checkout counter, then you would need a compatible app on your device that can write data into a tag.

Finally, once the UID and data have been written into the tag during programming mode, it will become ready for use in different environments for different purposes – such as at vending machines or in transportation systems. In addition to this important step of writing the UID and data into an NFC tag for usage in public places there are other additional steps that should be considered before starting the programming process. For example: security considerations like open or secure modes; battery power level; chip type; memory capacity allocated and types of interfaces used are all elements that need to be taken into consideration when doing any form of programming with tags.

NFC Tag Programming Tools


It is the process of writing content onto the tags. This can range from contactless payment data to simply launching a certain application. Programming NFC tags will require the use of specific tools and/or NFC-enabled devices, depending on the type of data you want to write. When it comes to NFC programming, two main categories exist: static and dynamic content.

Static content refers to data that is programmed onto an NFC tag once, such as a URL or contact information. Static content is best suited for tasks such as product identification or loyalty card data, where exact values need to be registered into an NFC tag and can’t be changed later. There are multiple ways of programming static content onto an NFC tag, but some of the most common methods involve using specialized software apps on a PC, or apps on mobile devices like Android smartphones or tablets that have near-field communication features built in.

Dynamic content refers to a piece of information that needs to be updated frequently over time by an authorized person. Dynamic NFC tags serve as a secure medium for transmitting encoded data back and forth between two devices without requiring physical contact between them each time.

One way in which dynamic tags are commonly used is in access control systems like parking meters, where users parking information can be easily transferred wirelessly with dynamic programming on modern era RFID technology cards embedded within smartphones compatible with this technology standard protocol based modules across different vendors ranging from proximity based applications steering towards automated car wash installations at variety of oil stations near metropolitan cities!

Programming NFC Tags with Computers

Programming them with your computer is an efficient way to add data to your tags quickly. There are two main ways to encode tags with your computer; using a NFC writer or a specific programming language.

For NFC writers, you need to have the correct type of writer for the type of tag you have along with access to the companion software that allows you to write tag data. First you will format the tag before writing data such as URLs, text strings and small files.

Alternatively, if you are working on a project that requires complex encoding of larger amounts of data such as images then a specific programming language may be preferred. For instance if you require the ability to generate cards or tickets then using Java Card technology may be beneficial as this allows for dynamic applet creation and other complex tasks with popular NFC cards.

When working with languages such as Java Card, it is important to know what type of card terminal that interfaces with the PC is required. Cards terminals also vary in capabilities – make sure it’s able to support the kind of applets/tools necessary for your project.



If you’re still unsure about the process or need help getting started, please feel free to explore more on this topic. We’ll take a look at your setup and be happy to provide fresh ideas or give further advice! To sum it up for your convenience:

  • It is a powerful wireless technology that enables two-way communication between devices.
  • There are different kinds of tags available depending on the application
  • Programming a tag requires specialized tools such as an NFC reader and writer
  • When using an Android device for writing data onto a tag, make sure that it has “NFC” written in its specifications section
  • Writing data onto an NFC tag requires understanding NDEF (NFC Data Exchange Format) messages
  • For security purposes consider enabling write protection on important tags that contain sensitive information
  • With practice you can build basic automation systems with just few lines of code

With this comprehensive guide at your disposal now you know almost everything there is to know about programming these tags! Have fun playing around with them!
