# Modules.Nfc.TagTechnologyNfcV
Provides access to NFC-V (ISO 15693) properties and I/O operations on a Modules.Nfc.NfcTag.
# Overview
Use the Modules.Nfc.createTagTechnologyNfcV method to create this tag technology.
See also: NfcV (opens new window)
# Properties
# apiName READONLY
The 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
