EID Tag Reader by MartEye

Read full description

Your livestock records, in your pocket. EID Reader by MartEye helps you record animal tags and keep them organised on your iPhone or iPad. Create a group, open a pen and start recording. Your records stay on your device, so you can keep working without an internet connection. RECORD EVERY ANIMAL Capture electronic tag numbers from a compatible reader or enter the full printed number by hand. Use No tag or Won't read to record animals whose tags are missing or unreadable. See the running count as you work. KEEP GROUPS AND PENS ORGANISED Create named groups for different jobs, flocks or batches. Add pens and notes, finish a pen and return to it later. Browse previous groups by date. SPOT DUPLICATES AND FIND RECORDS A repeat tag in the same group points you to its existing record or pen. Search saved pens, notes and tag numbers without leaving the app. SHARE YOUR RECORDS Export a whole group or a single pen as a CSV file. Save it to Files or share it using the apps on your device. CONNECT YOUR READER Open Supported readers for model-specific connection guides. Live scanning requires a compatible external livestock EID reader. Compatibility depends on the reader model, connection mode and firmware. You can use manual entry without a reader. BUILT FOR OFFLINE WORK No account is required to record, search or export tags.
