Quick answer: An Android smart terminal does not have the RJ11 drawer port that a traditional POS printer has — so a cash drawer cannot simply plug into a Qashier terminal. There are two working routes: a USB trigger (Qashier sells one, and it connects any drawer with a standard RJ11/RJ12 port), or an external receipt printer with a drawer port, which fires the drawer the conventional way.
The drawer itself is the easy part. Our NBCD-410 (410mm) and NBCD-460 (460mm) both use RJ11/RJ12 and ship in 12V or 24V. Decide the trigger route before you order, because it determines which voltage you need.
Why the drawer cannot plug straight into the terminal
On a traditional Windows till, the chain is: POS software → receipt printer → RJ11 cable → drawer. The printer supplies a pulse of current that energises a solenoid, a latch releases, and a spring pushes the drawer open. No data, just a jolt of electricity.
An all-in-one Android terminal like the QashierXS or QashierX2 has an integrated printer, but it is a compact mechanism built into the chassis — it does not expose the drawer-drive circuit and RJ11 socket that a standalone POS printer does. That is normal for this class of hardware, not a shortcoming of Qashier specifically. It does mean the drawer needs another way to get its pulse.
The two routes, and how to choose
| USB trigger | External printer with RJ11 | |
|---|---|---|
| What it is | A small adapter: USB into the terminal, RJ11 out to the drawer | A standalone receipt printer that also fires the drawer |
| Cost | Low — one accessory | Higher, but you get a printer |
| Choose when | The built-in printer is all you need and you only want a drawer | You need a second or kitchen printer anyway |
| Watch out for | USB ports on the terminal are limited — count what else needs one | Drawer opens when the printer prints, so the drawer must sit near that printer |
The port count is the practical constraint most people miss. A smart terminal has few USB ports. A scanner wants one. A trigger wants one. If you also need wired LAN, you are out of sockets. Qashier's expansion hub exists precisely for this — it allows a cash drawer, a LAN cable and a USB scanner concurrently. If your till needs more than one peripheral, plan the hub in from the start rather than discovering the limit on installation day.
The second route has a subtlety worth thinking through: if the drawer is fired by an external printer, the drawer opens where that printer is. Put the printer in the kitchen and the drawer opens in the kitchen. Fine when the external printer is a second front-counter till; wrong when it is a kitchen ticket printer. In that case, use the USB trigger.
12V or 24V: get this right before ordering
Cash drawer solenoids are built for a specific voltage. Whatever fires the drawer — trigger or printer — supplies one.
| Combination | Result |
|---|---|
| Matched (12V→12V, 24V→24V) | Opens crisply, every time |
| 12V source → 24V drawer | Usually will not open, or opens while the spring is new then stops weeks later |
| 24V source → 12V drawer | May open, running the coil over its rating — risks overheating over time |
The intermittent case is the one that costs money, because the drawer works on installation day and fails later, when nobody connects the two events.
Both our drawers are available in either voltage. It is a build option rather than a switch, so it has to be specified at order time — which is why we ask what you are firing it from. If you are going the USB trigger route, check the trigger's output specification with Qashier and tell us; if you are going the printer route, our printers state it (the NBTP-5830, for example, drives at DC 12V, 1A through a 6-pin RJ-11 socket).
Choosing the size
| Model | Width | Note |
|---|---|---|
| NBCD-410 | 410mm | Compact, for a tight counter. 4- or 5-position bill trays, 8-position coin tray. |
| NBCD-460 | 460mm | Standard full size. Up to 6 bill compartments, single- or double-row coin tray. |
Singapore and Malaysian notes fit both comfortably. The real question is compartment count and counter depth. A cafe taking mostly cards and PayNow, with cash as a minority of transactions, is well served by the 410 — it takes less counter and there is no prize for extra compartments you do not fill. A busy retail shop handling five or six denominations plus vouchers gets a faster cashier with the 460.
Both are steel with ball-bearing rollers, a front media slot for receipts and vouchers, and rated beyond a million operations. Browse the full cash drawer range.
A note on cash-light markets
Singapore is well down the road to cashless, and it is fair to ask whether a drawer is needed at all. Two reasons merchants still buy them, both practical rather than sentimental:
- A lockable place for cash that still arrives. Even at 10% of transactions, that cash has to live somewhere safer than a tin.
- It holds more than cash. Vouchers, cheques, card receipts requiring signature, petty cash slips — the front media slot exists for exactly this.
If cash is genuinely rare in your shop, the honest advice is to buy the smaller drawer, not to skip it. We would rather tell you that than sell you the bigger one.
Frequently asked questions
Can I connect a cash drawer directly to my Qashier terminal?
Not directly — the terminal has no RJ11 drawer port. Use a USB trigger, or connect the drawer to an external receipt printer that has the port.
Which cash drawer is compatible with Qashier?
Any standard drawer with an RJ11/RJ12 port, at the voltage your trigger or printer supplies. There is no software compatibility question — a drawer has no driver and no firmware.
The drawer opens sometimes but not always.
Classic under-voltage symptom, usually a 24V drawer fired from a 12V source. Confirm both specifications before investigating anything else.
The drawer does not open at all.
Check in order: voltage match; the drawer-open setting is actually enabled in whatever fires it; the cable is fully seated in the drawer port — not a network port, which is a genuinely easy mistake since the connectors are the same family; the key lock is not in the locked position.
I have run out of USB ports on the terminal.
This is the usual constraint on smart terminals. Qashier's expansion hub allows a cash drawer, LAN and a USB scanner at once — plan it in rather than discovering the limit at installation.
Can I open the drawer without making a sale?
That depends on the POS software rather than the hardware — the drawer opens whenever a pulse is sent. Ask Qashier how their app exposes a no-sale drawer open.
Does the drawer need its own power supply?
No. It takes the pulse from the trigger or printer over the cable.
A note on this guide. The drawer side above — solenoid voltages, the RJ11 pulse, port confusion, sizing — is what we know from the products we supply, and it holds for any POS regardless of platform. The Qashier-specific arrangements, including the USB trigger and expansion hub, are described from Qashier's published hardware information; confirm current accessory specifications and any no-sale drawer function with Qashier directly. If something here did not match your installation, tell us and we will correct this page. We would rather publish something accurate than something impressive.
