MediRead is currently available for use only with NFC-enabled Android smartphones. Apple does not yet allow general access to the NFC functionality in its iPhones. As and when this happens, an iOS version of the MediRead app will be released soon after. Recently, in June 2017, Apple announced that iOS 11 - expected to be released around Oct/Nov 2017 - will provide support for the reading of NFC devices, but not writing. At this point, we may release a read-only version of the app for iPhones 7 and above that will enable the information to be viewed through an iPhone.

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 wristband using the app. Thereafter, it is held physically on the wristband. There is no remote database or cloud server involved.

MediRead uses NFC (Near-Field Communication) technology. The wristband 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 wristband face, it is activated and the phone and wristband can communicate, enabling transfer of information to-and-fro. You enter information, write it onto the wristband and read/update it, all using the app.

The information you store on the wristband is held only on the wristband 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 wristband is lost, you can easily write the data onto a replacement. The data on the original wristband will remain, but will be of limited value to anyone other than yourself, emergency/medical staff and family members/carers.

Yes, the MediRead wristband is water 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 wristband, you request your doctor to download the app if they do not have it already. This will only take them a minute and the app is free.

The MediRead wristband is currently available in four sizes - Small, Medium, Large and Extra-Large. The four sizes have circumferences as below:
- Small - 160mm
- Medium - 176mm
- Large - 191mm
- Extra-Large - 220mm
We suggest that you measure the circumference of your wrist, add 10-15mm and choose a size based on that.

Yes, you can download the MediRead app on its own and activate the reminder facility via an in-app purchase. However, without the wristband, the utility in emergency situations is largely absent as there is no visible sign that you are carrying this vital information on your phone, which paramedics may not even have access to.

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

This is largely dependent on when Apple enables full NFC support within its iPhones. As and when Apple announces full NFC support, we will release an iOS version of MediRead soon after.

Update - Jun 2017: Apple has announced that it will support the reading of NFC devices starting with iOS 11 (iPhone 7/7+), expected to be released in Autumn 2017. At that point, we intend to release a read-only version of the app, but writing onto the bracelet will still require an Android phone.

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

Depending on enhancement requests we get from you and other users, we may produce periodic updates. As and when this happens, we will inform you by email 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.
