Accreditation for Android

Our accreditation software allows participants to print their credentials by QR code reading, or by searching for their name, email, or other search parameters. Printing usually takes from 3 to 7 seconds.

Technology Requirements

The technical requirements for accreditation vary depending on the format it will have at your event. It can be either self-service or with the support of promoters at each credential printing station.

The printer requires an internet connection in order to synchronize data.
Using a power supply that exceeds the recommended 110 V could potentially cause damage to your printer. To avoid this, it is important to ensure that the mains voltage used to power your printer falls within the required range. It is worth noting that the mains voltage supply can differ from one country to another. To determine the voltage requirements in your country, refer to this table.

If the voltage supply in your country is higher than what your printer requires, you can consider using a voltage converter to regulate the power. By taking these precautions, you can ensure that your printer operates safely and effectively.

We recommend images without texts so as not to confuse the attendees.

Setting the label type

There are 30 label templates that you can choose from. They vary in dimension, title and subtitle, and whether or not there is a QR code.

Under Title, Subtitle, and Extra, you will find the fields from your registration form to compose your credential information. Therefore, if you want content different from the default options, you must configure the registration form beforehand.

Setting up the badge details and accreditation behaviors

Other details
  • Alignment: Set whether the text lines are Left, Center, or Right aligned on the credential. This alignment does not affect the position of the QR code.
  • Caps- Lock: Set whether the contents of the credential will be all in caps-lock or will be as filled by the participant/organizer.
  • Has form: If you want your attendee to submit the registration form on the tablet, leave the Yes option selected. 
We do not recommend enabling this option on your tablet when tickets are sold.
  • Maximum print cap per attendee: Define how many credentials each attendee can print. 
The limit on the same tablet regardless of the configured limit will always be one. Therefore, if printing limits are above two, the attendee must perform the extra print at another point of service.
  • Search by: Choose the search parameter that your attendee will use in self-accreditation. If you want an option other than the attendees' Email, Name or email, or User, you must first configure the registration form.
  • Show partial results: If set to Yes, the system will return the 10 results linked to that search, whether complete or not. If No is set, the system only returns a result that is exactly the same as the search parameter.
For example, consider the name 'Ash the Astronaut' and that 'Search by' has been defined as 'Name or e-mail'. If set to Yes, the attendee who enters a part of the name ('Ash' 'Astronaut') can already find the first 10 results linked to these searches.  If set to No, the attendee will only find their credential when entering the complete name or e-mail.
  • Should print badge after NFC sync: If set to Yes, a badge will be printed after an attendee synchronizes their NFC band.
  • Should check-in after printing badge or syncing NFC: If set to Yes, the attendee will be checked-in once their badge is printed. You can also activate this option by clicking on the Settings button in the top right corner of the page and enabling Check-in post NFC.
