Titanium SDK # Modules.Nfc.TagTechnologyMifareClassic
Provides access to MIFARE Classic properties and I/O operations on a Modules.Nfc.NfcTag.
1.1.0# Overview
Use the Modules.Nfc.createTagTechnologyMifareClassic method to create this tag technology.
See also: MifareClassic (opens new window)
# Properties
# apiName READONLY
3.2.0The name of the API that this proxy corresponds to.
The value of this property is the fully qualified name of the API. For example, Titanium.UI.Button
returns Ti.UI.Button.
# lifecycleContainer
3.6.0The Window or TabGroup whose Activity lifecycle should be triggered on the proxy.
If this property is set to a Window or TabGroup, then the corresponding Activity lifecycle event callbacks will also be called on the proxy. Proxies that require the activity lifecycle will need this property set to the appropriate containing Window or TabGroup.
# tag
1.1.0The tag technology that has been discovered.
When a tag is discovered, a Modules.Nfc.NfcTag proxy is created and passed as a property to the onNdefDiscovered, onTagDiscovered, or
onTechDiscovered callback (see NdefDiscovered).
