The information on MediRead bracelets can be viewed using an NFC-enabled Android phone or an iPhone 7 or above. However, they can currently be written to only with NFC-enabled Android smartphones.

Apple does not yet allow full access to the NFC functionality in its iPhones. As and when this happens, an writable iOS version of the MediRead app will be released.

Support for Windows phones is not currently planned.

You can check if your Android phone has full NFC capability by looking for the model in www.nfcworld.com/nfc-phones-list/. You can also check your phone’s settings to determine this.

The information you enter is written onto your MediRead bracelet using the app. Thereafter, it is held physically on the bracelet. There is no website, remote database or other third-party involved.

MediRead uses NFC (Near-Field Communication) technology. The bracelet is a ‘passive’ device that is only activated when close to an electromagnetic field such as that around a smartphone. When your smartphone is brought to within 2-4 cms of the bracelet face, it is activated and the phone and bracelet can communicate, enabling transfer of information to-and-fro. You enter information, write it onto the bracelet and read/update it, all using the app.

The information you enter is held only on the bracelet and on your phone until cleared. As such, no third-party stores or maintains your data.

We would suggest you keep the information on your phone as well, so that, if your bracelet is lost, you can easily write the data onto a replacement. The data on the original bracelet will remain, but will be of limited value to anyone other than yourself, emergency/medical staff and family members/carers.

Yes, the MediRead bracelet is waterproof and dust-resistant and can be worn permanently if desired. Just make sure you get a size that does not make it too tight around the wrist.

Your doctor may or may not have the MediRead app. We recommend that, after having purchased your MediRead bracelet, you request your doctor to download the app if they do not have it already. This will take them less than a minute and the app is free.

The MediRead bracelet is currently available in four sizes - Small, Medium, Large and Extra-Large. The four sizes have inner circumferences as below:
- Small - 160mm
- Medium - 176mm
- Large - 191mm
- Extra-Large - 220mm
We suggest that you measure the circumference of your wrist, add about 10mm and choose a size based on that.

Yes, you can download the MediRead app on its own. However, without the bracelet, the utility in emergency situations is largely absent as there is no visible sign that you are carrying this vital information. Furthermore, your phone may be discharged, or paramedics and first-responders may not even have access to it.

MediRead uses NFC technology, which means that the bracelet is a ‘passive’ device that uses another device’s (usually a smartphone) electromagnetic field as its power source.

As of Nov '17, data on MediRead bracelets can be read using an iPhone 7 or newer. As to when the bracelets can be written to with iPhones is entirely dependent on when Apple enables full NFC support within its iPhones. We will release an full-function iOS version of MediRead soon after that happens.

No, each bracelet is intended for use by one person only. Having details of multiple people on one MediRead bracelet could be counter-productive in emergencies.

Depending on enhancement requests we get from you and other users, we may produce periodic updates. You will receive a notification as and when this happens, after which we would encourage you to download the latest version.

No, you can enter the name of any medication or allergy. The drop-downs are only provided for ease of data entry and to reduce errors in the same.

This is usually because the phone is more than the maximum scanning distance (2-4 cms depending on the phone) from the bracelet face. Placing the middle of the back of the phone against the bracelet face will almost always work. The location of the NFC chip inside the phone does vary though, so the easiest way is to check what scanning position at the back of the phone causes the app to open.

Note that, when reading the information using an iPhone, the scanning position is different and is usually near the top edge of the phone.
