Check Bitcoin Address Balance Tool
BitRef will help you to view the current balance of any Bitcoin address. You need only device with Internet and valid Bitcoin address string. This is safe service because it is using only public data, no need for login and password.
It is possible to monitor many Bitcoin addresses with one request. Just separate different addresses with "+" (plus) sign in the address field or in the URL. This way you can enter all your wallet addresses and monitor the entire wallet.
The tool shows last 50 transactions for every address (or combination of addresses). It shows the date, amount and current balance for every transaction. You can also check the number of confirmations by keeping the mouse pointer over the each transaction.
Use QR code or shortened URL address to bookmark address(es) information in your smartphone or tablet. Then you can monitor your address(es) from everywhere at any time with BitRef.
