Your TenX card cannot be used until it is activated and tied to your TenX account and wallet. This guide will walk you through the process. The screen captures are from a beta version of the webapp, but the process flow is similar across all versions of the TenX app.
To get started, tap on the Card button on the main screen of the app.
Scroll to the bottom of the screen and tap the link to activate your card.
Follow the prompts and enter the last 4 digits of your card number and the 16 digit number on your card insert. (Do not discard the insert until you are done. It is impossible to activate the card without the 16 digit number on the insert.) Tap the "Activate" button when you're done.
Congratulations! You now have a KYC level 1 approved card that's activated and attached to your TenX account, making your cryptocurrency spendable anytime, anywhere.
