About this app

Keep your cards organised with a private credit card wallet that works offline. Add cards manually, scan them with your camera, or read supported public EMV data through NFC. Card Wallet also includes an offline BIN checker, card validator, NFC tag reader, and four useful calculators.

💳 CREDIT CARD WALLET

Save credit and debit card details locally on your Android device. Choose a colour or gradient, add an optional nickname, view card details, delete one card, or clear the full wallet. Card numbers stay masked in the card list, with only the last four digits visible.

📷 CAMERA CARD SCANNER

Use on-device OCR to scan a card with your camera and fill in available details faster. Camera scanning works without an internet connection, and you can review the detected information before saving it to your credit card wallet.

📡 NFC CARD READER

Read publicly available data shared by supported contactless EMV cards. Some banks and cards provide only partial information, so the results may vary. The NFC card reader clearly handles devices with no NFC support or with NFC turned off.

This app only reads supported card information. It cannot make payments, enable tap-to-pay, or replace Google Pay.

🏷️ NFC TAG READER

Read supported NDEF and NFC tags, then view their available records and technical details.

🔎 OFFLINE BIN CHECKER

Enter the first 6 or 8 digits of a card number to run a BIN lookup against 340,000+ issuer ranges stored on your device. View available issuer, country, brand, card type, and category details. You can also copy the result, call the issuer, or open the issuer website.

✅ CARD VALIDATOR

Check a card number with the Luhn algorithm and detect its card network. This validation checks the number format only; it does not confirm that an account is active or that a payment will succeed.

🔐 PRIVATE, ENCRYPTED AND OFFLINE

Your saved credit card wallet data is encrypted with AES-256-GCM using Android Keystore. Card information stays on your device and is never uploaded, synced, or backed up. No account or sign-up is required, and you can clear all saved data from settings.

🧮 FOUR CALCULATORS

• EMI Calculator for monthly loan EMI
• GST Calculator for goods and services tax
• SIP Calculator for systematic investments
• Age Calculator for exact age

⚠️ RESPONSIBLE USE

Use the camera and NFC features only with cards you own or are authorised to use. This credit card wallet is a personal card organiser and information tool, not a payment service, bank, or financial institution.

Organise your cards, check BIN details, read supported NFC data, and use essential card tools—all in one offline credit card wallet.

🔒 YOUR DATA STAYS ON YOUR DEVICE

Card Wallet has no servers and no account. Every card you save is encrypted
with AES-256-GCM using the Android Keystore and stored only on this device.
Your card details are never uploaded, never synced, and never shared with us
or anyone else. All card features work fully offline.

Please note: because nothing is stored on a server, there is no cloud backup.
If you uninstall the app, clear its storage, or lose your phone, your saved
cards cannot be recovered.

The app connects to the internet only for ads, analytics and Google Play
purchases — never to send your card data.
