The choice of POS terminal for self-employed professionals will depend on the type of business and its specific needs, varying if it is a delivery driver, a plumber, or a taxi driver.
While the first case requires a more basic POS terminal, solely for charging customers and issuing physical receipts (e.g., the GPRS Mobile POS), the second does not require a POS that processes payments in different currencies or generates physical receipts (therefore, the Mobile POS would be a suitable option). In the third case, a more advanced POS is required, as payments in multiple currencies will be processed and physical receipts issued. The recommended option is the Android POS, as it supports AliPay and WeChat Pay.
