For Vietnamese entrepreneurs in Czechia

A checkout that understands Vietnamese.

Staff sell in a language they understand, customers receive clear Czech-facing product names, and moving from an old register does not mean starting over.

Keep what still works

Change the system, not the whole shop.

Sen Kasa starts by checking the devices and data you already have. We recommend replacing only what is genuinely incompatible.

Remote hardware check

Send photos of model labels and connectors on the scanner, printer, drawer and current register.

Reviewed catalog migration

Import products, prices, VAT, stock and barcodes with a preview before anything is saved.

Parallel pilot

Try Sen Kasa on one checkout while the existing system remains available as the fallback.

Compatibility, stated precisely

We do not call hardware compatible until the exact interface and model are known.

Ready

Network & Bluetooth ESC/POS printers

Print through a network address or a compatible Bluetooth printer.

Pilot validation

USB keyboard-mode scanners

The first grocery target; confirmed on physical hardware before live use.

Later phase

Integrated scales & scanner-scales

Require a specific protocol and metrology review; excluded from the first pilot promise.

One item, two contexts

Staff read Vietnamese. Customers receive Czech names.

An internal name makes the shift faster. The receipt name can be set separately for customers and accountants without rewriting sales history.

Not every business works the same way

One foundation, the right operating rhythm.

Groceries & convenience stores

Scanner-first checkout, barcodes, flexible pricing, inventory and fast unknown-item creation.

Restaurants & bars

Catalog, tables, tabs, courses and kitchen workflows appear only when the profile needs them.

Hair, nails & repairs

Services, customers and straightforward payment without restaurant features in the way.

Evidence over slogans

EET activates only after real verification.

Ordinary selling remains separate from fiscal registration. EET is currently held in a controlled test posture, with protocol version, test date and known limitations to be published clearly.

!Production EET is not currently enabled in Sen Kasa.

Playground first

Online submission, outage, retry, server rejection, refund and certificate scenarios on both platforms.

Selling keeps working

A missing certificate or EET configuration must never block an ordinary POS sale.

Stage the rollout

Begin with a small group, observe results, and expand only when the evidence supports it.

Pilot programme · limited to 25 businesses

The first 25 businesses will not migrate alone.

We are recruiting the first group of merchants to complete the hardware, catalog and real-world operating migration together.

✓Hardware review before buying replacements
✓Help migrating the catalog and barcodes
✓Vietnamese setup and guidance
✓Parallel testing beside the old system

Ask a question firstApplying is not a purchase commitment and does not guarantee that every old device will be compatible.

Common questions

Know before you change.

Do I need to throw away my current scanner and printer?+

Not necessarily. The exact model and connection determine whether it works directly, through an adapter, after software support, or should be replaced.

Is Sen Kasa already sending production EET?+

No. Production is locked. EET testing is clearly marked Playground until the official and release verification paths are complete.

Can the shop sell without internet?+

Ordinary POS operation is local-first so the shift does not depend on perfect connectivity. Sync and backup scope are described separately.

Does the pilot support retail scales?+

The first pilot focuses on standard barcode workflows. Direct scale integration requires separate protocol and metrology validation.
