Automatic Billing and Ticketing Devices Wireless Charger

Concept:

Now-a-days all the devices are portable in daily purposes may be handheld devices and automated. The handheld instruments like calculator, billing devices in hotels, restaurants, penalty fee receipts for traffic polices, ticket collectors in trains, ticketing devices for bus conductors, auto-rickshaw, movie theaters, bike and cycle parking receipts, entry tickets for parks, museums, shows, petrol/diesel billing at petrol bunks and soon required handheld devices for convenience. These all devices required charging, if this is wired for charging then we cannot make comfort move in the public due to plug and unplug for charging. So, if these devices are invented with wireless charging it will be more convenient.

Requirements:

The project require only mini USB connector, other hardware components are not necessary because the Wireless transmitter and receiver power modules have enough hardware circuitry and software programming.

Usage:

The swiping machine is connected with IDT Wireless receiver module with USB connector and placed on the transmitter pad. The billing machine is getting charging this makes the restaurants to bill their customers in an easy way in comfort. Figure 1 shows the charging pad in a restaurant charging the swiping machine.

Figure 2 shows the power connected option in the swiping machine

Applications:

The charging modules are very much necessary in restaurants because the machine is to be taken to the customers so it will be discomfort to plug the charger connector every time to the swiping machine. This charge modules can also be used in other types of ticketing and billing devices such as TIMs, Barcode readers, etc.
