What is ACR1251U NFC card reader?
Have you ever seen people swiping cards to open doors, eat meals, and take buses? Behind these magical “swiping cards”, there is actually a technology called NFC (near field communication).
ACR1251U is a “gadget” specifically used to read this kind of card – we call it an NFC card reader. You just need to bring the card close to it, and it can “recognize” the information in the card and help you complete operations such as opening doors, signing in, and paying, which is fast and safe.
What is special about ACR1251U?
No need to insert the card, just get close to it
It uses a wireless frequency called 13.56MHz, which is like a “secret channel” between it and the card. You don’t need to insert the card, just get close to it and it can “sense” it.
Plug it into the computer and use it
ACR1251U connects to the computer via a USB interface, just like plugging in a USB flash drive. Plug it in and use it, without installing a bunch of complicated software.
It can be used on Windows, macOS, Android and iOS, supports most operating systems on the market, and is almost not picky about devices.
Supports multiple card types
No matter what card you use, it can basically read:
Common access control cards (such as MIFARE 1K/4K)
Student ID, library card
NFC mobile phone stickers or tags
Various contactless cards that follow the ISO 14443A/B standard
That is to say, whether you are in the company, school, hospital, or in the mall, subway, you can use it.
Small and light, convenient to put anywhere
The whole machine is only the size of a palm (about 9.8 cm long) and weighs only 73 grams, which is almost as light as a bag of sugar. Whether it is placed on the desk or embedded in other devices, it does not take up space.
Where can it be used?
Office access control: Employees swipe their work cards to open the door, which is safe and fast.
School system: Students swipe their cards to enter the campus, borrow books, and eat.
Stores and supermarkets: customers swipe cards to pay, redeem points, and verify membership.
Self-service machines: self-service printing, self-service check-in, self-service inquiry… can all use it to sense cards.
