1. Уводзіны
This manual provides essential information for the proper use and maintenance of your 5YOA 13.56MHz Rewriteable UID RFID Keyfobs. These keyfobs are designed for duplicating and rewriting IC card data, specifically targeting the Sector 0 Block Zero (UID block) of compatible cards. Please read this manual thoroughly before attempting to use the keyfobs to ensure correct operation and to avoid potential issues.
2. Прадукт скончыўсяview
The 5YOA UID Rewriteable Keyfobs function similarly to standard IC cards, adhering to the Mif 1K S50 standard. Their unique feature is the ability to arbitrarily modify Sector 0 Block Zero, which contains the card's Unique Identifier (UID). This allows for duplication and cloning of compatible RFID cards using an appropriate read-write device.

4. Настройка і падрыхтоўка
To utilize the rewriteable functionality of these keyfobs, you will need a compatible RFID read-write device. Ensure your device supports 13.56MHz frequency and is capable of modifying Sector 0 Block Zero of Mif 1K S50 standard cards.
- Сумяшчальная прылада: Use a dedicated RFID copier/writer.
- Несумяшчальныя прылады: Please note that Android MCT applications or any standard mobile phone will NOT work for writing to these UID keyfobs.
- Уключэнне: Ensure your RFID read-write device is powered on and ready for operation.
5. Інструкцыя па эксплуатацыі
Follow these steps to read and write data to your 5YOA UID Keyfobs using a compatible RFID writer:
- Read Original Card: Place the original IC card (the one you wish to duplicate) onto the reading area of your RFID writer. Press the 'Read' or 'Scan' button on your device. The device should display the card's UID and other data.
- Verify Data: Confirm that the device has successfully read the data, especially the UID from Sector 0 Block Zero.
- Prepare Keyfob: Remove the original card and place a 5YOA UID Rewriteable Keyfob onto the writing area of your RFID writer.
- Запіс дадзеных: Press the 'Write' or 'Copy' button on your device. The device will then program the UID and other copied data onto the keyfob.
- Пароль па змаўчанні: If prompted for a password for Block 0, the default password is
FFFFFFFFFFFF(12 F's). - Праверка: After writing, you may re-read the newly programmed keyfob to ensure the data has been successfully transferred and matches the original card.

6. Тэхнічнае абслугоўванне
To ensure the longevity and proper functioning of your 5YOA UID Keyfobs, please follow these maintenance guidelines:
- Захоўваць сухім: Avoid exposing the keyfobs to water or high humidity, as moisture can damage the internal chip.
- Пазбягайце экстрэмальных тэмператур: Do not expose keyfobs to extreme heat or cold, as this can affect their performance and durability.
- Асцярожна звяртайцеся: While durable, avoid bending, dropping, or subjecting the keyfobs to strong impacts, which could cause physical damage.
- Акуратна чысціце: If cleaning is necessary, wipe with a soft, dry cloth. Do not use harsh chemicals or abrasive materials.
7. Выпраўленне непаладак
- Keyfob not writing/reading:
- Ensure your RFID writer is compatible with 13.56MHz Mif 1K S50 standard cards.
- Make sure the keyfob is placed correctly on the reading/writing area of the device.
- Check if the RFID writer has sufficient power.
- Verify that the original card is not encrypted in a way that prevents duplication of Block 0. - 'Android MCT or any phone won't work with UID' error:
- This is a known limitation. These UID keyfobs require a dedicated RFID read-write device and are not compatible with mobile phone applications for writing. - Incorrect data after writing:
- Re-read the original card to ensure the data was captured correctly.
- Ensure the keyfob remained stationary on the writer during the entire writing process.
- Try writing again. - Keyfob not recognized by target system:
- Double-check that the original card is indeed a 13.56MHz Mif 1K S50 compatible card.
- Verify that the target system accepts cloned UIDs. Some advanced systems may have additional security measures.
8. Карыстальніцкія парады
Хоць канкрэтных карыстальнікаў нямаviews or Q&A were provided for this product, here are some general tips for using rewriteable RFID keyfobs:
- Test Immediately: After programming a keyfob, test it on the intended reader or system as soon as possible to confirm successful duplication.
- Backup Original: Always keep your original card safe. If possible, create a digital backup of the original card's data using your RFID writer's software before attempting to clone.
- Зразумейце абмежаванні: Be aware that not all RFID systems are compatible with cloned UID cards, especially those with advanced anti-cloning features.
