About NFC TagWriter by NXP
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 [email protected] if you have problems. 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.
