We love NFC! That's why, we strive to provide the most simple and usable solution to read NFC-Tags. NFC21 Reader focuses on the content of a scanned NFC-Tag and offers an action to proceed immediately – without any distractions whatsoever. NFC tags are used to store information like website links, phone numbers, business cards or WiFi configurations. NFC21 Reader enables you to read and interact with such nfc tags in just two easy steps: First, by scanning the NFC tag, you get a preview of its contents. Second, execute an action matched to the given content. For example, to open a weblink in Safari, import a business card into contacts or show a location in maps. NFC21 Reader supports the following Tag-Types: • URL: Website Links to open in Safari. • VCard: Business cards, that may be added to your contacts. • WiFi: Network configuration to easily join a secured WiFi. • Text: Short texts that can be copied to the clipboard. • GEO: Location that is shown in maps application. • Phone Number: To easily dial a stored phone number. • Mail: Create a new mail with prefilled address and subject. • SMS: Start a new SMS-chat with a given phone number. We improve the application continuously and add more types and actions. Do you miss a feature? Our development team would love to listen to your idea! NFC-Expert?
