# Usage
NOTICE: As of v1.3 uFR Browser Extension, usage has been changed.
New function uFR_Request(command) has been implemented and its usage is strongly suggested instead of ufRequest function.
Call uFR_Request function and pass "command" parameter as string that contains UFCoder function.
uFR_Request example:
```javascript
async function ufrTest() {
let response = await uFR_Request("ReaderOpen");
}
```
Instead of using callback of ufRequest function to get data from our reader via extension, uFR_Request function will wait for
command to finish and store data in functions assigned variable(e.g let response in this example).
uFR_Request is a Promise-based function which will wait for it to resolve, in other words, function will wait for data to be received from the reader with the 'await' keyword.
uFR Browser Extension v1.3 can still be used with ufRequest-ufResponse functions used in older extension implementations:
```javascript
uFRequest(command, function () {
let response = uFResponse();
})
```
