#Frequently Asked Questions about POS Cash Register Systems

Below are common questions from business owners when first investing in a POS system, from hardware integration capabilities to data security.

Can the POS cash register system integrate with an electronic scale?

Yes. Most modern POS systems support connecting electronic scales via RS232 or USB ports. When weighing products, the weight will automatically transfer to the POS software and calculate the price. This feature is especially useful for food stores, fruit shops, or agricultural product retailers.

Does the POS system work when there is no internet?

Yes. Việt POS's POS system supports offline mode, allowing sales and local transaction storage. When internet connectivity is restored, data automatically synchronizes to the server. This ensures business operations are not interrupted, which is particularly important for stores in suburban areas or regions with weak network coverage.

Việt POS provides data migration services for customers. The process includes: exporting data from the old system (Excel, CSV, or API), mapping product categories, verifying, and importing into the new system. Completion time ranges from 1-3 business days depending on the data volume.
