The NFC TagWriter by NXP stores contacts, bookmarks, geo location, Bluetooth Handover, SMS, Mail, text messages and many more to any NFC-enabled tags as well as to items like posters, business cards, watches and many more containing NFC-enabled electronics. Once data has been stored the application allows also reading and viewing the programmed data including options to launch applications automatically based on the contained data.

NOTE: Installing TagWriter on a non-NFC enabled phone is enabled now but it does of course not allow you to actually program tags. Anyhow, you can now prepare NFC data sets e.g. on a large screen device and then share them with an NFC enabled handset to actually make use of them. Besides that you can catch a pre-view on what you could do with a handset supporting NFC.
Please contact us at if you have problems, if you don’t find things you seek for and feel free to contact us if you like things, too. We will continue our efforts to add new features for your benefits and we work hard to provide a feature rich application ahead of other apps available in the market.

    Great app, previous version was perfect, we recommended it to every of our customers. However after the recent release, permanent protect (lock) function, if chosen during the write operation, fails to lock the tag everytime. Must do it separately by invoking the function from Lock menu. This is annoying. We tried with NTAG203 and Ultralight, both are the case.

    NXP: are you guys the new Microsoft or Apple? WTF is wrong with you? Forcing me to stop using the old version whenever NXP updates this app? You know this is my smartphone, you can't dictate what your users can or can't do. And be decent with your tong next time.

    Still learning about NFC, but was able to start writing tags 30-seconds after installation. The workflow takes a little getting used to. This app is powerful and has options that I haven't figured out yet.
