Attendances vs AttenQR

Attendances is a cloud-based attendance system for schools, colleges, and other institutions, available on Android and the web. It records attendance using AI face recognition, QR-code ID cards, or biometric devices, and can match uploaded student photos without a separate enrollment session. The site says scans take roughly 200–300 milliseconds and support more than 60 people per minute. Schools can configure class-wise automatic absence rules and get daily lists of students who missed check-in or check-out. Reports can be filtered by device, student, class, or date and exported to PDF or Excel. Parents may receive School eDiary push notifications when students are marked in or out; SMS costs extra. Photo settings range from sharing no images to sharing scan images or capturing live photos at each scan. Packages include selected parent-app and ERP modules. When internet access drops at a gate, scans queue on the device, but notifications wait until connectivity returns. Pricing is by school-specific quote, and a trial account can be set up with a school's own data.

AttenQR is an attendance system for classes that uses QR codes to record check-ins and enroll students. Students scan the daily attendance code, and teachers see check-ins appear in real time; a separate permanent code lets students join a course. Teachers can share courses with other teacher accounts to manage attendance together, then export records to CSV. The service is available on Android, iOS, and the web, and supports English, Spanish, Korean, Chinese, and Japanese. It has a free plan at free, while a one-time payment of 9.99 USD removes ads permanently; that premium status is tied to a user account and cannot be transferred. Ads are shown through Google AdMob, and the maker says attendance may not be recorded if a student closes the ad after scanning before it finishes. Course and attendance information is kept in US Firebase Cloud Firestore with encryption in transit and at rest and access controls. Data is automatically deleted 30 days after a course ends, so teachers can export it beforehand.
