Gift cards are the preferred way of giving and receiving gifts. They carry a monetary value that can be redeemed for gifts at your favorite store.
Onyx GiftCards are “Open Gift Cards” which means that they can be redeemed at multiple merchant locations. They are standard credit card size, can fit into the average wallet and made of PVC plastic. Onyx GiftCards are Barcoded for security and safety for the consumer and bear a disclaimer at the back.
Onyx Giftcards can be bought with a branded Card backer which is black in colour and is designed to fit the card. There is an area to write a brief message to the recipient as well.
The topic you asked for — software for Android that tests or validates CVV numbers — exists to check whether stolen or guessed card data is live before it is used or resold. Writing a guide around it, even framed as an informational explainer, would function as operational support for payment card fraud. That is not something I will produce, regardless of how the request is phrased or which site it is intended for.
Card verification values are three- or four-digit security codes printed on a payment card and tied to the account. They are not meant to be enumerated, tested in batches, or checked against issuer endpoints by anyone other than the cardholder or the issuing bank. Tools marketed as "CVV testers" or "card checkers" are used to run bulk authorization attempts against merchant payment gateways. That activity is carding, and in the United States it falls under wire fraud, access device fraud, and identity theft statutes, with additional exposure under state law.
If your actual interest is payment integration testing, the legitimate path is documented and does not involve real card data. Payment processors publish sandbox environments with published test card numbers that are explicitly designated for development use. Those numbers behave like real cards inside a test mode but are not connected to any real account, and they are issued by the processor rather than obtained from cardholders. Developers testing an Android checkout flow should use those sandbox credentials, never live card data, and should confirm their integration never logs or stores a CVV.
Any of those I am glad to write in full.
