RFID Access Control Keypad – Card + Password Door Lock System

Description

The SMQ-303 RFID Access Control Keypad is a compact and reliable standalone access control system designed for secure door entry management.

It supports both RFID card access and PIN password entry, allowing flexible security options for homes, offices, shops, and commercial buildings.

With storage support for up to 500 user cards, it is ideal for small to medium-scale installations. The built-in doorbell button allows connection to an external bell for added convenience.

The device features LED indicators to display working status (Power / OK), ensuring easy monitoring and system operation.

Its durable keypad and strong outer casing make it suitable for long-term indoor or semi-outdoor installations.

The standard 12V keypad, and the one most doors actually need. This is our entry level RFID and PIN access control unit, running on the 12V supply that the great majority of small commercial installations in Pakistan use. For an internal office door, a store room, a shop back area, or any sheltered doorway, this does everything the more expensive keypads do at the lowest price in our range.

Where it fits, and where it does not. Choose this for doors in sheltered positions: internal corridors, office doors, store rooms, back of house areas, and entrances under a proper canopy. Do not choose it for a fully exposed external door or gate, where sun, monsoon rain, and dust will eventually get into a plastic housing. For those, our metal bodied S602EM is built for the job and worth the difference. We would rather tell you that now than replace a failed reader in a year.

Check your voltage first. This unit runs at 12V DC, which covers most small commercial access control. If your site runs 24V, which is common on industrial premises, some gate systems, and installations with long cable runs, you need our 24V version instead. Connecting a 12V unit to a 24V supply damages it. Look at the label on your existing power supply, or send us a photograph and we will confirm which you need.

Card and PIN, and how businesses actually use them. The keypad accepts RFID cards and numeric PIN codes. Most premises settle on cards for permanent staff who pass through many times daily, and a rotating PIN for cleaners, contractors, and occasional visitors. The practical advantage over keys is removal: when someone leaves, you delete their card or change the PIN in seconds instead of replacing a cylinder and reissuing keys to everyone else. In a business with any staff turnover, that alone usually justifies the system within the first year.

Standalone, with nothing to subscribe to. Users are stored on the keypad itself. No server, no software licence, no internet connection, and no monthly fee, and it keeps working regardless of whether your broadband does. Each door is managed at its own unit, which is why this arrangement suits one or two doors well. If you grow to many doors or need attendance reporting, ask us about networked controllers instead.

The keypad is not the lock. This is the controller. A working door also needs the lock itself, an exit button on the inside so people can leave, and a power supply rated for everything on the door. Glass and aluminium doors normally take a magnetic lock; wooden doors usually take an electric bolt lock. Ordering the keypad on its own is the most common reason an electrician arrives and cannot complete the installation, so we supply matched kits with the lock, button, and supply included.

Fail safe or fail secure, decided by the lock. During load shedding a magnetic lock releases and the door opens, while a fail secure bolt lock stays shut. Neither is automatically correct. An escape route should generally release; a store room protecting stock should generally stay locked. Decide this when you specify the door, and fit a backup supply or emergency break glass release accordingly.

Mounting and cable. The reader sits on the unsecured side of the door by definition. Run the cable in conduit and keep it inaccessible, because an exposed cable behind a reader lets someone bypass the entire system without touching the keypad. Seal the cable entry so moisture cannot track into the terminals.

Choosing between our keypads. This standard 12V unit for sheltered doors on a budget. The 24V version if your system runs at that voltage. The metal bodied S602EM for exposed external doors and gates. The T11 where its feature set suits your requirement. Tell us the door location and your supply voltage and we will point you to the right one rather than the dearest.

Can I fit this outside? Only in a genuinely sheltered position. For exposed doors, choose the metal bodied unit.

How do I know if I need 12V or 24V? Check the label on your power supply or send us a photograph of it.

Does it need internet? No, it stores users on the device and operates entirely offline.

What lock should I buy with it? Magnetic for glass and aluminium, electric bolt for wooden doors. Send a photograph of the door and we will confirm.

Can it record attendance? It is designed for access control. Ask about biometric attendance machines if you need timekeeping.
