No, it isn't a 'chip' from the local casino, it is a Bitcoin. Bitcoin is a payment system (actually a decentralized digital currency) that refers to itself as "currency for the world." Payments work from one individual or business to another individual or business, without a central repository or single administrator.
One reason that Bitcoin is becomming so popular is the fees are lower than those typically imposed by credit card processors, other other monetary exchanges. Bitcoins are stored on your computer or mobile device in a Bitcoin wallet, and when you start using Bitcoin the wallet will generate a Bitcoin address which can be passed to anyone, but each address is used only once.
It really isn't necessary to fully understand all the complexities of how Bitcoin serves as a replacement for 'other' currencies, you simply need to know that Bitcoin lets you exchange 'value' in a different way than via traditional banks or merchant services.
Late last week Intuit announced that QuickBooks Online has become the first cloud accounting solution to enable small businesses to accept Bitcoin payments. This functionality occurs as a result of a new integration between QuickBooks Online and Coinbase, the largest and fastest-growing Bitcoin wallet service in the United States.
Intuit's PayByCoin is now available as a free add-on for small business operators who use QuickBooks Online to generate electronic invoices. After registering with CoinBase, QuickBooks Online users link their BitCoin wallets to their existing account. When a customer receives and invoice they receive the option to pay by Bitcoin, as well as traditional methods such as credit card.
